I have a Lenovo ThinkPad T430 running Red Hat Enterprise Linux 6.5, kernel 2.6.32-431.30.1.el6.x86_64, and my filesystem structure consists of a master LUKS partition holding two logical volumes, one for the root filesystem formatted as Ext4, another for the swap space. Per corporate policy I must run Symantec Antivirus and IBM Tivoli Endpoint Manager, the former of which I disable prior to hibernating because SAV interferes with hibernation (compliance is not an issue because Symantec Antivirus automatically restarts after I wake my computer).
As of lately it has been happening to me that after waking my system from hibernation, my root filesystem becomes corrupted and Linux reacts by remounting it read-only. When this happens I must stop everything, restart my computer and wait for
fsck to fix the corrupted filesystem. So far I have yet to experience information loss but I would very much like to correct this issue before it causes greater trouble.
My disk is perfectly healthy according to GNOME2's Disk Utility, so I don't believe it could be that my HD is about to fail.
