[Gluster-users] incorrect usage value on a directory

Thu Sep 15 11:23:24 UTC 2016

Hi Sergei,

You can set marker "dirty" xattr using key trusted.glusterfs.quota.dirty. You have two choices:

1. Setting through a gluster mount. This will set key on _all_ bricks.

[root at unused personal]# gluster volume info
No volumes present
[root at unused personal]# rm -rf /home/export/ptop-1 &&  gluster volume create ptop-1 booradley:/home/export/ptop-1/
volume create: ptop-1: success: please start the volume to access data
[root at unused personal]# gluster volume start ptop-1
volume start: ptop-1: success

[root at unused personal]# mount -t glusterfs booradley:/ptop-1 /mnt/glusterfs
[root at unused personal]# cd /mnt/glusterfs
[root at unused glusterfs]# ls
[root at unused glusterfs]# mkdir dir
[root at unused glusterfs]# ls
dir
[root at unused glusterfs]# setfattr -n trusted.glusterfs.quota.dirty -v 1 dir
[root at unused glusterfs]# getfattr -e hex -m . -d dir
# file: dir
security.selinux=0x73797374656d5f753a6f626a6563745f723a6675736566735f743a733000

[root at unused glusterfs]# getfattr -e hex -m . -d /home/export/ptop-1/dir/
getfattr: Removing leading '/' from absolute path names
# file: home/export/ptop-1/dir/
security.selinux=0x756e636f6e66696e65645f753a6f626a6563745f723a686f6d655f726f6f745f743a733000
trusted.gfid=0xbea41d7780e4445e93dc379b0a43bb7a
trusted.glusterfs.dht=0x000000010000000000000000ffffffff
trusted.glusterfs.quota.dirty=0x31

2. If you find usage wrong only on an individual brick, you can just set the xattr on the backend directly. For eg., in the volume above, we can also do,
setfattr -n trusted.glusterfs.quota.dirty -v 1 /home/export/ptop-1/dir

regards,
Raghavendra
