Hi, we have multiple clusters of GlusterFS which are mostly alike. The typical setup is as such:
- Cluster of 3 nodes - Replication factor of 3 - Each node has 1 brick, mounted on XFS with RELATIME and NODIRATIME - Each node has 8 disks in RAID 0 hardware The main problem we are facing is that observation of the access time of a file on the volume will update the access time. The steps to reproduce the problem are: - Create a file (echo 'some data' > /mnt/gv0/file) - Touch its mtime and atime to some past date (touch -d 19700101 /mnt/gv0/file) - Touch its mtime to the current timestamp (touch -m /mnt/gv0/file) - Stat the file until atime is updated (stat /mnt/gv0/file) o Sometimes it's instant, sometimes it requires to execute the above command a couple of time On the IRC channel, I spoke to a developer (nickname ndevos) who said that it might be a getxattr() syscall that could be called when stat() is called on a replicated volume. Anybody can reproduce this issue? Is it a bug, or is it working as intended? Is there any workaround? Thank you, Simon
