Disk errors on SDS

ci flag

My database (mysql) server, wich is a VPS, is experimenting disk errors every couple of days. It automatically mounts /dev/sda2 in read-only mode.

I have to connect vía ssh and run fsck /dev/sda2 to correct the errors and then reboot.

The errors that apper are like this:

Inodes that were part of a corrupted orphan linked list found.

Deleted inode 788641 has zero dtime.

Block bitmap differences:  -3266667 -(5107712--5109276)
-(5113856--5115903) -(5117952--5118444)

Free blocks count wrong for group #99 (21307, counted=21308).

Free blocks count wrong (2124203, counted=2131998).

Inode bitmap differences:  -787904 -787907 -787962 -788605 -788607
-(788634--788638) -(788641--788644) -(788674--788676) -1182418 -1182603 -(1189802--1189803)

Free inodes count wrong for group #96 (67, counted=84).

Free inodes count wrong (1083016, counted=1083012).

I read in other posts that the HDD is dying and should replace it. But the VPS server is using SDS disk, so no physical disk is being used.

Any clues of what could be producing these errors? Or any method I can use to know more about them?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
