[15:47] <jrwren> fsck says a fs is in use. it doesn't show as mounted. What to do?
[15:48] <cmaloney> Fire is always an option
[15:48] <cmaloney> Any way yo single-user mount that FS?
[15:53] <jrwren> it isn't mounted. I nkow I could reboot, but I'm trying to learn deeper what is going on.
[15:58] <cmaloney> does lsof on the device show anything?
[15:59] <jrwren> nope. it doesn't show as mounted.
[15:59] <cmaloney> I mean the /dev/ device
[15:59] <jrwren> but interestingly, lvchange -a n does the same.
[15:59] <jrwren> nope.
[15:59] <cmaloney> huh
[15:59] <cmaloney> is it a RAID?
[16:00] <cmaloney> womdering if mdadm might be playing with it
[16:00] <cmaloney> but if lsof doesn't show anything then I'm at a loss for what's going on.
[16:00] <jrwren> yeah, it is LVM. I don't even have mdadm installed.
[16:01] <jrwren> i've never run lsof on a device. i'll have to make sure I'm checking that correctly.
[16:01] <cmaloney> Not as familiar with LVM, but wondering if it's doing some rebuilding
[16:01] <cmaloney> but I would think it would leave some note as to using the device.
[16:02] <cmaloney> Yeah, lsof on a device is kinda useless
[16:03] <jrwren> oh, i see. lsof works as if I specified the mount point.
[16:03] <jrwren> no no, lsof on a device works great.
[16:03] <cmaloney> not on my machine. :)
[16:04] <cmaloney> lsof /dev/sdc doesn't do squat
[16:04] <jrwren> well, I guess files on that device do have to be opened, but when they are, it found it for me.
[16:04] <cmaloney> right
[16:04] <cmaloney> bbiab
[16:07] <jrwren> it sucks, cuz I can mount it and then unmount it and get the same results :(
[16:14] <jrwren> oh ffs. some LVM PVs are actually missing. *sigh* but missing devices don't show in pvs output AND lvs shows all volumes as sync 100%
[16:14] <jrwren> fucking terrible. it is no wonder people spend $$$$$$$$$$ on netapp and EMC
[16:42] <cmaloney> Yipes
[16:43] <cmaloney> or go with ZFS on BSD
[16:43] <cmaloney> https://unix.stackexchange.com/questions/489182/lvm-pv-missing-after-reboot
[16:43] <cmaloney> This should not be a FAQ
[17:47] <jrwren> I fear ZFS on any kernel will be worse.
