Bug 65235

system.journal

Very interesting.  This is exactly the sort of corruptions I am seeing in my journal data.  I have to systems running multiboot on the same hardware.  One is a very basic Mageia 3 64bit system running on ext4.  It has zero problem with journal corruptions.  The other is my main system, a 32bit Mageia 3 system running on 64bit Intel hardware.  The file system is exclusively btrfs raid 1 configuration.  On this system I get a constant flow of corruptions that look exactly like what Hussam is seeing.  The corruptions typically occur 89-95% into the verify scan.  What is interesting is that I am not seeing any problem with the actual logs, only with the verifies.  But I am finding that once these corruptions accumulate to a certain point the journal logging system itself dies.  I have had that happen once already and was only able to restore it by cleaning out the old journal files.  Since I can't trust the journal on this system, I am running rsyslog as a backup.

I use ext4. ext4 is very solid right now so I don't believe that is the source of my problem.

Fixed (at least the "failure" shown by journalctl --verify for the attached journal file) in http://cgit.freedesktop.org/systemd/systemd/commit/?id=92fba83e.

in systemd 205 it now says:
journalctl --verify
