Hi David,
With this feature enabled, the consistent time attributes (mtime, ctime, atime) will bemaintained in xattr on the file. With this feature enabled, gluster will not used time
attributes from backend. It will be served from xattr of that file which will be
consistent across replica set.

Hello Kotresh,its no problem for me that the atime will be updated, importat is a consistent mtime and ctime on the bricks of my replica set.I have turned on both options you mentioned. After that I created a file on my FUSE mount (mounted with noatime). But on all my bricks of the replica setthe mtime and ctime is not consistent. What about the brick mount? Is there a special mount option?I have a four node cluster and on each node there is only one brick. See below all my volume options:Volume Name: test1

What kind of options are not allowed if I want to mount a volume? There is "noatime,realatime" mentioned. Does the second mean "relatime". I never heard of "realatime". Is there any recommendation for the mount options?RegardsDavid Spisla
