[Gluster-users] df does not show full volume capacity after update to 3.12.4
After OS update to CentOS 7.4 or RedHat 6.9 and update to Gluster 3.12.4, the ?df? command shows only part of the available space on the mount point for multi-brick volumes. All nodes are at 3.12.4. This occurs on both servers and clients. We have 2 different server configurations. Configuration 1: A distributed volume of 8 bricks with 4 on each server. The initial configuration had 4 bricks of 59TB each with 2 on each server. Prior to the update to CentOS 7.4 and gluster 3.12.4, ?df? correctly showed the size for the volume as 233TB. After the update, we added 2 bricks with 1 on each server, but the output of ?df? still only listed 233TB for the volume. We added 2 more bricks, again with 1 on each server. The output of ?df? now shows 350TB, but the aggregate of 8 ? 59TB bricks should be ~466TB. Configuration 2: A distributed, replicated volume with 9 bricks on each server for a total of ~350TB of storage. After the server update to RHEL 6.9 and gluster 3.12.4, the volume now shows as having 50TB with ?df?. No changes were made to this volume after the update. In both cases, examining the bricks shows that the space and files are still there, just not reported correctly with ?df?. All machines have been rebooted and the problem persists. Any help/advice you can give on this would be greatly appreciated. Thanks in advance. Eva Freer -------------- next part -------------- An HTML attachment was scrubbed...

Sam, For du ?sh on my newer volume, the result is 161T. The sum of the Used space in the df ?h output for all the bricks is ~163T. Close enough for me to believe everything is there. The total for used space in the df ?h of the mountpoint it 83T, roughly half what is used.

Hi Eva, Can you send us the following: gluster volume info gluster volume status The log files and tcpdump for df on a fresh mount point for that volume.

Hi Eva, One more question. What version of gluster were you running before the upgrade?
