Patch 5 has been respun with the recommended change... remove the ex argument in ocfs2_orphan_scan_lock() and ocfs2_orphan_scan_unlock(). Sunil

I can reproduce this in my local VM. I've traced ocfs2_dismount_volume and found that it hasn't been called. So EBUSY is returned in VFS layer. I guess something wrong when doing a copy with linked SQEs (normal copy seems no problem). Thanks, Joseph On 2/24/23 8:32 AM, Heming Zhao wrote: > Hello List, > > I found a weird bug on ocfs2.

Hi, All, These four patches are all related to ocfs2 on hard readonly mount. patch 1 fix oops when umount ocfs2 on hard readonly device. Because ocfs2_dismount_volume() will call ocfs2_cluster_hangup() and then call ocfs2_stack_driver_put(), will hit BUG_ON(active_stack == NULL). patch 2 fix oops when do ls or cat in ocfs2 on hard readonly device. Because ocfs2_open_lock() will call ocfs2_cluster_lock() and then call ocfs2_dlm_lock(), but active_stack is NUL...

In commit ea455f8ab68338ba69f5d3362b342c115bea8e13, we move the dentry lock put process into ocfs2_wq. This is OK for most case, but as for umount, it lead to at least 2 bugs. See http://oss.oracle.com/bugzilla/show_bug.cgi?id=1133 and http://oss.oracle.com/bugzilla/show_bug.cgi?id=1135. And it happens easily if we have opened a lot of inodes. For 1135, the reason is that during umount will call

Dear Sirs and Madams, I run a small visual effects production company, Hammerhead Productions. We'd like to have an easily extensible inexpensive relatively high-performance storage network using open-source components. I was hoping that OCFS2 would be that system. I have a half-dozen 2 TB fileservers I'd like the rest of the network to see as a single 12 TB disk, with the aggregate

Hello List, I found a weird bug on ocfs2. I am busying with other jobs, if anyone have time he/she could fix it. This bug is blocking fstest generic/013 test case, and also blocking fstest to do later test cases. How to trigger: ``` git clone git://git.kernel.dk/liburing.git cd liburing make cd examples mount -t ocfs2 /dev/sda /mnt cp /etc/hosts /mnt/a ./link-cp /mnt/a /mnt/b umount /mnt ```
