I have a client on cloud hosting with some sizable drives on the vps. Twice in the past year after a forced reboot the server was down for a few hours because
fsck ran automatically when the server came back up. Since this is on a cloud hosting platform I am assuming that there are other integrity checks performed on the disk at the hardware level. The host indicated that there are differences between an integrity check at the infrastructure level and OS level, and that they strongly recommended that
fsck not be disabled. However, the client is concerned because very large amounts of downtime result in customer and revenue loss.
It looks as if I can disable those checks by running the following commands:
tune2fs -c 0 -i 0 /dev/mapper/vgArchiveStorage-archive tune2fs -c 0 -i 0 /dev/mapper/vg_maindisc-lv_root
Would this fix the issue, and if so, how bad of an idea is it to do so? Is there a way to do similar periodic checks without actually bringing the whole server offline (both disks are integral to the operation of his website).
