Re: [Touch-packages] [Bug 1681410] Re: fstrim corrupts ocfs2 filesystems when clustered

I tried disabling fstrim on all but one server and had the exact same issue as I did when cron enabled it on all servers. - Original Message - From: "Nick Stallman" <1681...@bugs.launchpad.net> To: "Kyle O'Donnell" Sent: Tuesday, August 1, 2017 7:49:49 PM Subject: [Bug

[Touch-packages] [Bug 1681410] Re: fstrim corrupts ocfs2 filesystems when clustered

I think we've also had a related issue. We haven't had any serious corruption but we have had random locks that never get released which requires a server reboot to clear. OCFS2 does support trim, as does our SAN. I think the issue may be related to running fstrim in parallel however. I didn't

Seeing the same thing with OCFS2 on Oracle VM Server 3.3.3. Clustered OCFS2, but on one device and only one node (Clustered when setup, but then the cluster portion wasn't utilized due to licensing) -- You received this bug notification because you are a member of Ubuntu Touch seeded

[Touch-packages] [Bug 1681410] Re: fstrim corrupts ocfs2 filesystems when clustered

It is one device. We have 2 luns for 2 different ocfs2 filesystems mounted on all servers (6) in the cluster. It is presented via fiber channel from our SAN. I think the issue is that if you run fstrim from all servers which are mounting the same ocfs2 filesystem at the same time, bad stuff

[Touch-packages] [Bug 1681410] Re: fstrim corrupts ocfs2 filesystems when clustered

I'm thinking that the bug is in the OCFS2 filesystem driver. Since it can span multiple disks, both local and remote, it can not give a sensible answer to the FIBMAP ioctl when fstrim asks what blocks a file is located in. Please test this by creating a file and checking where FIBMAP says it is
