Hi all,
I have a linux debian server that has been working without a hitch until this weekend. The server has an LVM with two sata drives sda and sdb. Basically the server has been restarting multiple times over the weekend, with the error sdb: unknown partition table as the last entry in the syslog and kern.log files.
From what I have read, this could be a sign that the partition table could be going bad.

I restarted the server cold this morning and has been up, but the error message still comes up every 5 minuttes

I have been trying to look for a solution, but came up empty handed.

If anybody can point me in the right direction it would be greatly appreaciated.

Thanks!

Partition tables do not "go bad", but drives most certainly do.

Run smartctl -a /dev/sdb | less and look for errors. In particular, look for the line saying "SMART overall-health self-assessment test result". Anything other than "PASSED" means the drive needs to be replaced immediately.

Also, the following parameters may tell you if the drive is bad, even if the self-assessment says "PASSED":

Reallocated_Sector_Ct (should be 0 or at least in the single-digits)

Reallocated_Event_Ct (as above)

Current_Pending_Sector (a drive going bad will show a non-zero value)

Power_On_Hours (consumer-class drives cannot be expected to last more than 2 to 3 years, which translate to 17,520 and 26,280 hours respectively)

Makes sense, I did run smartmon and everything looked good.I will look at the results closer.
