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