xfs下开启目录配额之后不生效-马春杰杰

今天遇到了一个bug，某个盘是xfs格式的，之前一直好好的，可以直接使用sudo xfs_quota -x -c "report -h" /NFSshare查看目录配额，结果今天不知道怎么回事，死活查看不了了，观察挂载情况，也是显示noquota：

(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare
/dev/sda1 on /NFSshare type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
(base) root@VPMS-Lab-NAS:~# xfs_quota -x -c "state" /NFSshare
(base) root@VPMS-Lab-NAS:~# cat /proc/mounts | grep NFSshare
/dev/sda1 /NFSshare xfs rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota 0 0
(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare
/dev/sda1 on /NFSshare type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
(base) root@VPMS-Lab-NAS:~# umount /NFSshare
(base) root@VPMS-Lab-NAS:~# mount -o usrquota,grpquota,prjquota /dev/sda1 /NFSshare
(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare

(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare

/dev/sda1 on /NFSshare type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)

(base) root@VPMS-Lab-NAS:~# xfs_quota -x -c "state" /NFSshare

(base) root@VPMS-Lab-NAS:~# cat /proc/mounts | grep NFSshare

/dev/sda1 /NFSshare xfs rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota 0 0

(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare

/dev/sda1 on /NFSshare type xfs (rw,noatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)

(base) root@VPMS-Lab-NAS:~# umount /NFSshare

(base) root@VPMS-Lab-NAS:~# mount -o usrquota,grpquota,prjquota /dev/sda1 /NFSshare

(base) root@VPMS-Lab-NAS:~# mount | grep NFSshare

搞得我差点以为是内核不支持，想了想，最近也没升级内核啊。

直到无意间发现，/dev/sda1除了/NFSshare这个目录，竟然还挂载了另一个：

(base) root@VPMS-Lab-NAS:~# mount /NFSshare
mount: /NFSshare: /dev/sda1 already mounted on /vol00/ST1000DM003-1SB102.

1 2	(base) root@VPMS-Lab-NAS:~# mount /NFSshare mount: /NFSshare: /dev/sda1 already mounted on /vol00/ST1000DM003-1SB102.

恍然大悟，绝对就是它了，这是飞牛OS默认挂载的路径，并且是没有开启配额的。

所以，只需要全部umount，然后重新mount就行了~

(base) root@VPMS-Lab-NAS:~# umount /vol00/ST1000DM003-1SB102
(base) root@VPMS-Lab-NAS:~# umount /NFSshare
(base) root@VPMS-Lab-NAS:~# mount /NFSshare

(base) root@VPMS-Lab-NAS:~# umount /vol00/ST1000DM003-1SB102

(base) root@VPMS-Lab-NAS:~# umount /NFSshare

(base) root@VPMS-Lab-NAS:~# mount /NFSshare

终于可以了：

(base) root@VPMS-Lab-NAS:~# sudo xfs_quota -x -c "report -h" /NFSshare
