Strange die hard

Question

Iron

Or maybe it doesn’t die ... in general, such a situation - not so long ago, after updating the axis core on the server after reboot, I noticed that one of the disks was not mounted, I looked at dmesg -> http://pastebin.com/idqVmfj1 I think - that's it, screw sailed while I remembered what lay on the screw and what was backed up from it, some time passed and I was suddenly twitched to try to mount it with my hands. here I am his hop

mount -t xfs -U b5ae87ef-30a6-4439-ac94-1b347cf016ca /mnt/sde

and he calmly mounted

kernel: XFS (sde1): Mounting Filesystem
kernel: XFS (sde1): Starting recovery (logdev: internal)
kernel: XFS (sde1): Ending recovery (logdev: internal)

I worked without complaints for about two weeks, and today it was necessary to reboot the server again and the screw did not rise again, but I remember that the screw is mounted manually - I tried to mount it, but in the end I got the same hell - Can't find superblock on / dev/sde1. After some time (~30 minutes) - I tried to mount it again and it was mounted and continues to work normally again ... what kind of mystic? Plows 24x7 all year. I can not understand - why does it start working normally after a while !? Maybe it's not a screw of wine at all, maybe a power supply unit?

upd : the screw turned out to have nothing to do with it, the point is in the controller, more precisely in one of the ports. Swapped places with CD - everything is perfectly mounted.

Answer 1

If the screw is more than 3 years old and problems begin, then we remove it and put the screw on a shelf.

Answer 2

If you say that it works 24x7, maybe it's just overheating.
