Title:
Trusty linux-image-3.13.0-164-generic:amd64 breaks XFS project quota
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello,
the recent Trusty update to Linux Kernel linux-
image-3.13.0-164-generic:amd64 breaks XFS project quota. They used to
work wih the exact same configuration and still work in Trusty with a
Wily 4.2 HWE Kernel.
The symptom is the following:
$ sudo xfs_quota -c 'df -h'
XFS_GETQUOTA: No such process
Steps to reproduce (on Ubuntu 14.04.5 LTS with Kernel 3.13.0-164-generic /
Ubuntu 3.13.0-164.214-generic 3.13.11-ckt39):
$ dd if=/dev/zero of=xfs.pquota.test bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 0.671311 s, 1.6 GB/s
$ mkfs.xfs xfs.pquota.test

$ sudo mount -o loop,pquota xfs.pquota.test /mnt/
$ mkdir /mnt/prj1000
$ echo '1000:/mnt/prj1000' | sudo tee -a /etc/projects
1000:/mnt/prj1000
$ sudo xfs_quota -x -c 'project -s 1000'
Setting up project 1000 (path /mnt/prj1000)...
Processed 1 (/etc/projects and cmdline) paths for project 1000 with recursion
depth infinite (-1).
$ sudo xfs_quota -c 'df -h'
Filesystem Size Used Avail Use% Pathname
/dev/loop0 1014M 32.2M 981.8M 3% /mnt
XFS_GETQUOTA: No such process
The last line should have been the quota information for project 1000, as it
used to be.
