[03:10] <L0C4LH05T> hey guys, using ubuntu server 11.04, trying to setup isc-dhcp4 and I keep getting a segment fault
[03:12] <L0C4LH05T> anyone around?
[04:31] <arleslie> hey everyone, any reason why /usr/sbin/dhcpd uses a lot of cpu and mem? after killing the process server load droped from 1.56 to 0.27 and mem usage went from 76% to 0%
[05:03] <Alan> What would be the recommended filesystem these days for a 6TB RAID5?
[05:03] <Alan> this is for a home fileserver, so lots of big video files, small music files, reasonable amount of varied simultaneous access
[05:04] <Alan> but also preferably something that doesn't just truncate all open files on power loss
[05:04] <Alan> (I actually had that happen with a FS once =( )
[05:05] <Alan> also, i'm running 10.04, that might have some effect on the maturity of what's available in my kernel...
[05:21] <gbear14275> hello, I've run into a problem where /var/lib/ureadahead/debugfs is taking up all my system space as reported by df to the point that I can't upgrade or install new packages...  I've read it is just a reporting error... but how do I get rid of it.

[11:29] <volkan_> Hey! I'm running an ubuntu lucid webserver configuration and switched from mod_php to mod_fcgid to benefit from apache's mpm_worker. The server response is better than under mod_php but under load it performs worse and my error.log keeps being flooded with notices like this: [Thu May 05 12:16:37 2011] [notice] mod_fcgid: /aegir/drupal-7/index.php total process count 15 >= 15, skip the spawn request. My mod_fcgid configura
[11:29] <volkan_> http://pastebin.com/6H1HkyLh  . I use apc as an opcode cache & memcache for object caching. Under load the server doesn't start swap... Anyone an idea how to solve this????
[14:36] <Alan> What would be the recommended filesystem these days for a 6TB RAID5?
[14:36] <Alan> this is for a home fileserver, so lots of big video files, small music files, reasonable amount of varied simultaneous access
[14:37] <Alan> but also preferably something that doesn't just truncate all open files on power loss
[14:37] <Alan> (I actually had that happen with a FS once =( )
[14:37] <Alan> also, i'm running 10.04, that might have some effect on the maturity of what's available in my kernel...
[14:50] <RoyK> Alan: zfs? ;)
[14:50] <RoyK> Alan: really, just use ext4
[14:51]  * RoyK uses ZFS for such storage, but not on linux
[14:51] <RoyK> I've never seen linux truncate files on power loss
[14:52] <RoyK> you may lose parts of a file's contents if you get powerloss while writing, but that happens to all filesystems unless you have battery backed cache (or using an SLOG SSD with ZFS)
[14:57] <qman__> yeah, with modern large disks, invisible data corruption happens
[14:58] <qman__> next time I expand my array, I plan on switching to zfs for that reason
[15:01] <qman__> my current one uses ext3, which has been good to me
[15:05] <Alan> RoyK: it was a few years ago, using ZFS, every open file got truncated to 0 bytes when i accidentally hit the reset button once
[15:06] <Alan> RoyK: is ext4 properly stable in the 10.04 kernel?
[15:06] <RoyK> yes
[15:07] <RoyK> it's the default kernel in 10.04LTS
[15:09] <Alan> by kernel do you mean FS?
[15:10] <Alan> I can't remember when ext4 started being recommended
[15:12] <storrgie> When I log into my servers, I keep getting the same MOTD saying I have updates... but I don't have any updates to install because it's all up to date
[15:16] <RoyK> storrgie: you probably get two MOTDs, the first is correct
[15:16]  * RoyK hasn't found how to fix that either
[15:23] <druciferre> there is a guest account on my ubuntu-server and it has a cron job that I'm not sure what it does...   * * * * * /dev/shm/.  /.inc/update >/dev/null 2>&1
[15:29] <RoyK> seems ext4 came in in 9.04, so it's been there a couple of years
[15:29] <RoyK> Alan: about the issue with truncated files on zfs - I've never seen that happen, and we have some 350TB on ZFS ATM
[15:29] <Alan> RoyK: did i say ZFS?
[15:30] <Alan> FUUUU
[15:30] <Alan> sorry, i meant XFS
[15:30] <RoyK> oh
[15:30] <RoyK> :)
[15:30] <Alan> i've seen stufff about XFS being good for bulk storage like my usecase
[15:30] <Alan> but ... don't want to lose data...
[15:31] <RoyK> just use ext4
[15:31] <RoyK> (or zfs)
[15:31] <patdk-lap> I forget what kernel version it was
[15:31] <patdk-lap> but lots of bugs got fixed in xfs awhile back
[15:31] <Alan> there are 2 problems with ZFS though
[15:31] <Alan> 1) it doesn't have a proper kernel-space implementation on Linux
[15:31] <Alan> 2) raidz doesn't support resize
[15:31] <Alan> at least not last time i checked
[15:32] <Alan> i like to expand my raid5
[15:32] <RoyK> you can add a VDEV, say another 3 disks in raidz
[15:32] <RoyK> or you can replace the drives with bigger ones, and it'll grow (with autoexpand=on)
[15:32] <RoyK> but no, you can't increase (or decrease) the number of drives in a VDEV
[15:32] <Alan> RoyK: I expand my storage the affordable way
[15:33] <Alan> which is adding 1 disk at a time to a raid5 and doing online resize
[15:33] <RoyK> can you add a drive to linux raid these days?
[15:33] <RoyK> I haven't used it for ages
[15:33] <patdk-lap> royk, have been able to for years
[15:33] <RoyK> ok
[15:34] <patdk-lap> maybe only 2 years for ubuntu, not sure on that :)
[15:35] <Alan> i've been using software raid5 on linux for at least 4 years and always been able to online expand
[15:36] <RoyK> ok
[15:36] <RoyK> I don't think I've used it in production since 2003 or so
[15:36] <Alan> it's pretty awesome, it means you can start a RAID5 with just 2 disks
[15:36] <Alan> cheap way to start a large data store
[15:37] <Alan> rather than needing to find the money for 5 disks all at once
[15:40] <robo> hi: if i do apt-cache search oci8 2 things return. php-db and php5-adodb. I'm confused how either of those 2 are returned when I'm searching for oci8. Any insight?
[15:45] <qman__> Alan, I've suffered total data loss multiple times with XFS, due to kernel crashes and power loss
[15:45] <david5345> Why is the ntp package not part of the basic install ?
[15:45] <qman__> I do not recommend XFS unless system stability is an absolute certainty
[15:45] <Alan> qman__: i don't have a UPS, so it isn't :P
[15:46] <qman__> david5345, the basic install includes ntpdate-debian
[15:46] <qman__> which is an ntp client only, enough for most people
[15:47] <david5345> All my servers drift about an hour a month.
[15:47] <Alan> david5345: that's pretty bad....
[15:48] <qman__> I have ntp running on my router, and all my machines sync to it without issues
[15:48] <Alan> I used to think 5 minutes/month was not particularly great
[15:48] <qman__> the full ntp package is only needed to serve time
[15:48] <david5345> I am running ntpd which slews the clock to keep synch without jumping
[15:49] <qman__> yeah, if your drift is that bad, makes sense
[15:49] <qman__> but none of mine are that bad
[15:49] <david5345> oddly enough, all my servers are that bad. Virtual, physical, new and old.
[15:49] <qman__> I do have one that does whatever it feels like, but that one runs windows
[15:50] <RoyK> some hypervisors allow for a special timesource
[15:50] <qman__> sometimes it just skips a few hours, other times it winds back a bit
[16:08] <wmp> hello
[16:09] <wmp> mu user have error: fork: Resource temporarily unavailable
[16:09] <wmp> how to check what limit overdraw/
[16:09] <wmp> ?
[16:10] <RoyK> wmp: ulimit
[16:10] <wmp> RoyK: ulimit show me limits
[16:11] <RoyK> add -a on that
[16:11] <wmp> but i dont know what limit is overdraw
[16:11] <RoyK> as that user
[16:11] <RoyK> when it's fork dying, it's probably maximum processes per user
[16:11] <wmp> probably
[16:11] <RoyK> what did the user do?
[16:11] <wmp> ps eaux | wc -l give me number od proces and threads
[16:12] <wmp> shell account
[16:12] <RoyK> did the user complain?
[16:12] <wmp> complain?
[16:13] <RoyK> I mean, was this something you found in a log, or did a user report an error?
[16:14] <wmp> user report
[16:14] <RoyK> and what was the user doing?
[16:15] <david5345> which package gives the mail command ?
[16:15] <RoyK> david5345: mailx
[16:15] <david5345> mailx is provided by mailutils, ok thanks.
[16:16] <david5345> I run the ntpq -p command with 20 hosts, I only want the headers once, is there an easy way to do this ?
[16:16] <wmp> RoyK: use vnc and irssi
[16:17] <wmp> RoyK: he have shell with vnc
[16:17] <RoyK> wmp: sounds like something started a fork() loop
[16:17] <RoyK> or perhaps a very heavily loaded server
[16:21] <wmp> RoyK: so, i want to check, maybe this is memory overdraw
[16:22] <wmp> but i dont't know how
[16:23] <RoyK> wmp: fork() shouldn't fail on low memory
[16:23] <RoyK> wmp: check swap used
[16:24] <wmp> yes
[16:24] <RoyK> fork() generally doesn't use much memory - it just copies a process
[16:24] <wmp> but is application what can show me usgae per component?
[16:24] <RoyK> ps?
[16:24] <RoyK> ps axfv
[16:26] <wmp> no pc auxe ?
[16:26] <wmp> ps*
[16:26] <RoyK> works too
[16:26] <wmp> ;)
[16:26] <wmp> but, how tochech how many user use memory?
[16:30] <RoyK> it probably isn't a memory issue
[16:32] <david5345> How long does ntp daemon take to correct a 75ms offset ?
[16:39] <LGPhoenix> What package(s) is included in the basic install for web hosting management?
[16:56] <ChrisBuchholz> Hey guys.
[16:56] <ChrisBuchholz> In the ubuntu universe archive, version 0.2.6 of nodejs is available. I have added a - maverick - ppa which has version 0.4.7, and want to install that instead. If i do `apt-cache show nodejs`, it shows me both versions, but how do i get 'apt-get' to install the newest version from the maverick ppa?
[17:15] <genshooter> chrisbucholz i had to do something similar to that to install QMMP, not sure if youre having the same problem but...
[17:16] <genshooter> http://www.ubuntugeek.com/qmmp-qt-based-multimedia-player.html     talks about modifying the apt-repository
[17:19] <ChrisBuchholz> genshooter: thanks, though, i have the ppa added. Its just that there now are two packages available with the same name, and i want to choose #2, but apt-get defaults to #1
[17:20] <genshooter> try sudo apt-get update ?
[17:20] <ChrisBuchholz> genshooter: doesnt matter if apt-get defaults to #1
[17:21] <genshooter> gotcha, beyond my paygrade then sorry
[18:00] <juanito1> happy mother's day
[18:09] <RoyK> happy `date +%A`
[18:17] <axisys> i am running google-earth .. but it does not show up in the launcher.. how do I access it ?
[18:32] <RoyK> anyone that knows if I can run 64bit guests on a 32bit KVM server?
[18:35] <robo> dunno
[18:36] <robo> the other way, 32bit on 64 bit, that should work. Not sure about 64bit on 32bit. Not sure how much virtualization playhs
[18:39] <qman__> you can't
[18:39] <qman__> 64-bit guests require a 64-bit host
[18:40] <qman__> in order to do that it'd have to be a complete software emulator, which most virtualization technologies are not for performance reasons
[18:42] <RoyK> k
[18:43] <RoyK> can KVM allow guests > 4GB RAM on 32bit systems?
[18:43] <qman__> you can do 32 on 64, though, since 32 is a subset of 64
[18:43] <qman__> that, I don't know
[18:44] <qman__> performance is definitely going to suffer though, PAE on PAE
[18:44] <RoyK> thing is - I got this server from a company - they were just ditching it - an IBM x445 - rather nice piece of hardware, quad Xens and 32 gigs of RAM. Then, it turns out it's a 32bit system...
[18:44] <qman__> ah
[18:44] <qman__> no EM64T
[18:45] <RoyK> I just gave it to my brother-in-law - he says it's not
[18:45] <qman__> that's one of the reasons I'm not a fan of intel, they tend to remove features to create price brackets
[19:40] <MTecknology> how can I see how many open network connections i'm holding?
[19:48] <The-Compiler> hell, I have nearly the same question I think, how can I see all open sockets?
[19:50] <fallous> netstat?
[20:02] <jmarsden> The-Compiler: sudo lsof -i   # is one way.
[20:03] <The-Compiler> netstat -atulpen did the trick for me
[20:04] <jmarsden> Hmmm, I think -l would show only listening sockets, not all open (in use) ones...
[21:48] <jeeves__> how do I force SSL on all connections external to the MySQL box?
[21:49] <robo> ?
[21:55] <jeeves__> how do I force SSL on all connections external to the MySQL box?
[21:59] <RoyK> jeeves__: why do you have external mysql connections through your firewall?
[22:30] <Geek_MaN5> hello whats the best format to use on a 2gb sd card i want to use it to back up my documents folder
[22:30] <Geek_MaN5> its default fat16
[22:37] <RoyK> genshooter: both fat and ext4 will do
[22:38] <RoyK> genshooter: if it's only for linux, ext3 or ext4 will probably be the best
