Description of problem: the quota is ineffective while mount ext4 fs with delalloc option， but if I mount ext4 fs with nodelalloc,the quota is effective. Version-Release number of selected component (if applicable): Fedora-11-Alpha How reproducible: Steps to Reproduce: 1.mkfs.ext4 /dev/sda7 2.mount -t ext4 -o usrquota /dev/sda7 /mnt 3.quotacheck -avug 4.quotaon -avug 5.setquota -u quser1 5 10 0 0 /mnt 6.chmod 777 /mnt 7.su quser1 8.dd if=/dev/zero of=/mnt/file count=30 9.sync Actual results: # quota -u quser1 Disk quota for user quser1(uid 501) Filesystem blocks quota limit grace files quota limit grace /dev/sda7 16 5 10 7days 1 0 0 0 Expected results: # quota -u quser1 Disk quota for user quser1(uid 501) Filesystem blocks quota limit grace files quota limit grace /dev/sda7 10 5 10 7days 1 0 0 0 Additional info:
Reassigning to kernel component. Thanks & regards, Phil
commit 60e58e0f30e723464c2a7d34b71b8675566c572d apparently fixes this
(In reply to comment #2) > commit 60e58e0f30e723464c2a7d34b71b8675566c572d apparently fixes this I don't consider the patch fixes the problem already, i tested the patch
That commit has a lot of dependencies.... You might test the latest Rawhide kernel to see if it's working better, it should have all of the upstream quota fixes to date. -Eric
From some brief testing, the 2.6.30 kernel should have this fixed (or at least working better? For very small quota values I see some issues, but it generally seems to be working) I won't be able to pull those chagnes into the initial F11 release, but when the .30 kernel hits F11 as an update it should be fixed. Sorry for not having it working in GA, we'll add a release note about this issue. Closing RAWHIDE for now, if you can test a rawhide kernel and still encounter quota bugs, please let me know. Thanks, -Eric
Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Quota on ext4 filesystems is not working correctly when the default delayed allocation mode is enabled. Mounting with -o nodelalloc should resolve this issue in the near term, and the upstream 2.6.30 will have this fixed properly for a future F11 kernel update.
