The http://unix.stackexchange.com/questions/98208/i-o-errors-on-linux-lvm server goes dead at night requiring a forced reboot or power cycle to restore service. If it matters, this server has 1 large RAID-6 volume with 1 global hot spare available.I believe I have error on narrowed this issue down to the MegaRAID controller being busy with a RAID rebuild, and some automated action occurring at night that confuses LVM into oblivion. The issue is difficult to narrow down because this “automated action” seems to result in all file systems being marked read-only. Syslog seems to continue working, but obviously cannot write useful data out to disk. Hence I have only been able o error on to collect data on those rare times that I can actually log in when this issue occurs. I was able to capture 2 points of data that seem to start out with the same error condition.This only seems to occur when a drive fails and the MegRAID rebuilds to the global hot spare, or if I force some action on the RAID which causes a drive fail and rebuild to an alternate disk (I had a few disks get SMART predictive failures and have been working to replace these with new). I initially thought this issue was related to smartd warning messages, however when I replaced the last drive with predictive failures, the rebuild triggered the same behavior.So what seems to be the pattern is that I kick off a rebuild (which takes many hours) and then sometime around midnight a systemd-udevd process kicks in and the system eventually ends up unresponsive. From the 2 times I was able to get on, these messages seem to be in common right at the time file systems go read-only:Jul 15 00:45:44 server1 kernel: megaraid_sas: scanning for scsi0...Jul 15 00:45:44 server1 systemd-udevd: failed to execute '/sbin/mdadm' '/sbin/mdadm -If sda5 --path pci-0000:09:00.0-scsi-0:2:0:0': Input/outpu

One of them is getting the error: Oct 30 10:57:07 alpha01 kernel: lost page write due to I/O error on dm-3 Oct 30 10:57:07 alpha01 kernel: Buffer I/O error on device dm-3, logical block 4 Which is causing problems with all of the LVs on it. pvs shows the PV as unknown device. I can ls to the logical volumes and they show up in lvdisplay, but first I get a bunch of IO errors. I made sure the cables are secure between the USB drive. What should I do to get this back up and running for the meanwhile? Should I unmount each LV and run an fsck.ext4 on each one like fsck.ext4 -y /dev/vg1/lv_logvolname ? linux lvm fsck share|improve this question asked Oct 30 '13 at 15:06 Gregg Leventhal 2,29032752 In addition to fsck, if the external drive is SMART capable, checking the drive status/health and running the drive self tests may be useful. Backing up all the data may also be important. –rickhg12hs Oct 30 '13 at 15:44 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted I usually don't go the route of running an fsck and assume the disk is failing or has bad sectors. I definitely wouldn't run the fsck using the -y, since this will give fsck to attempt to start moving blocks which may exacerbate the problem. Instead I'll run a tool such as Spinrite (Commercial) or HDAT2 (freeware) on the disk to do the analysis & potential repair. What else? See my other answers to these questions for additional methods: fsck -cc /dev/sdb1 gives this result.
