Jan,
since i can not cc you mail address when filing a bug on oss
bugzilla,just paste the bug description here.
Testing env,
Kernel version:latest linus's mainline 2.6.27
Testing Nodes:test5/6
Description:
Jan,i used your provided quota tools,now it works for me:),currently,i'm
doing a sanity check for the quota on ocfs2.
Found a strange thing when comparing with the ext3,the quota sub-system
sometimes did not warn me a tip when the soft-limit of space usage was
exceeded.following are the steps to reproduce this issue:
1.mkfs.ocfs2 --fs-features=usrquota,grpquota ... /dev/sdc5
2.mount -t ocfs2 -o usrquota,grpquota /dev/sdc5 /quota
3.useradd -m quotauser
4.setquota -u quotauser 1024 2048 10 20 -a /dev/sdc5
5.quotaon -avug
6.su - quotauser; cd /quota
7.
dd if=/dev/zero of=./testfile1 bs=1024 count=1024
1024+0 records in
1024+0 records out
1048576 bytes (1.0 MB) copied, 0.00825239 seconds, 127 MB/s
dd if=/dev/zero of=./testfile2bs=1024 count=10
sdc5: warning, user block quota exceeded.
10+0 records in
10+0 records out
10240 bytes (10 kB) copied, 0.000133629 seconds, 76.6 MB/s
at the first attempt,it successfully warn me a tip:
sdc5: warning, user block quota exceeded.
8.then I REMOVE all the dd created files by 'rm -rf testfile*',and try
again with the same operations:
dd if=/dev/zero of=./testfile1 bs=1024 count=1024
1024+0 records in
1024+0 records out
1048576 bytes (1.0 MB) copied, 0.00831317 seconds, 126 MB/s
dd if=/dev/zero of=./testfile2 bs=1024 count=10
10+0 records in
10+0 records out
10240 bytes (10 kB) copied, 0.000135853 seconds, 75.4 MB/s
***here a warning should be printed to output******
quota
Disk quotas for user quotauser (uid 501):
Filesystem blocks quota limit grace files quota limit
grace
/dev/sdc5 1056* 1024 2048 6days 2 100
200
is that strange?
Thanks and regards,
Tristan.
