Hi all, I have an issue where our volume will not start from any node. When attempting to start the volume it will eventually return: Error: Request timed out For some time after that, the volume is locked and we either have to wait or restart Gluster services. In the gluserd.log, it shows the following: [2017-12-15 18:00:12.423478] I [glusterd-utils.c:5926:glusterd_brick_start]

Hi all, I'm taking a stab at deploying a storage cluster to explore the Halo AFR feature and running into some trouble. In GCE, I have 4 instances, each with one 10gb brick. 2 instances are in the US and the other 2 are in Asia (with the hope that it will drive up latency sufficiently). The bricks make up a Replica-4 volume. Before I enable halo, I can mount to volume and r/w files. The

Here's the volume info: Volume Name: gv2a2 Type: Replicate Volume ID: 83c84774-2068-4bfc-b0b9-3e6b93705b9f Status: Started Snapshot Count: 0 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: gluster1:/bricks/brick2/gv2a2 Brick2: gluster3:/bricks/brick3/gv2a2 Brick3: gluster2:/bricks/arbiter_brick_gv2a2/gv2a2 (arbiter) Options Reconfigured: storage.owner-gid: 107

For what it's worth here, after I added a hot tier to the pool, the brick sizes are now reporting the correct size of all bricks combined instead of just one brick. Not sure if that gives you any clues for this... maybe adding another brick to the pool would have a similar effect?

The sizes of the files are extremely varied, there are millions of small (<1 MB) files and thousands of files larger than 1 GB. Attached is the tier log for gluster1 and gluster2. These are full of "demotion failed" messages, which is also shown in the status: [root at pod-sjc1-gluster1 gv0]# gluster volume tier gv0 status Node Promoted files Demoted files

I should add that additional testing has shown that only accessing files is held up, IO is not interrupted for existing transfers. I think this points to the heat metadata in the sqlite DB for the tier, is it possible that a table is temporarily locked while the promotion daemon runs so the calls to update the access count on files are blocked?

Thanks for the info, Hari. Sorry about the bad gluster volume info, I grabbed that from a file not realizing it was out of date. Here's a current configuration showing the active hot tier: [root at pod-sjc1-gluster1 ~]# gluster volume info Volume Name: gv0 Type: Tier Volume ID: d490a9ec-f9c8-4f10-a7f3-e1b6d3ced196 Status: Started Snapshot Count: 13 Number of Bricks: 8 Transport-type: tcp Hot

Hi Tom, The volume info doesn't show the hot bricks. I think you have took the volume info output before attaching the hot tier. Can you send the volume info of the current setup where you see this issue. The logs you sent are from a later point in time. The issue is hit earlier than the logs what is available in the log. I need the logs from an earlier time. And along with the entire tier

Hi, I'm testing gluster 3.12.4 and, by inspecting log files /var/log/glusterfs/mnt-gv0.log (gv0 is the volume name), I found many lines saying: [2018-01-15 09:45:41.066914] I [MSGID: 109063] [dht-layout.c:716:dht_layout_normalize] 0-gv0-dht: Found anomalies in (null) (gfid = 00000000-0000-0000-0000-000000000000).

Hello Nithya! Thank you for your help on figuring this out! We changed our configuration and after having a successful test yesterday we have run into new issue today. The test including moderate read/write (~20-30 Mb/s) and scaling the storage was running about 3 hours and at some moment system got stuck: On the user level there are such errors when trying to work with filesystem: OSError:

Hello Nithya! Thank you so much, I think we are close to build a stable storage solution according to your recommendations. Here's our rebalance log - please don't pay attention to error messages after 9AM - this is when we manually destroyed volume to recreate it for further testing. Also all remove-brick operations you could see in the log were executed manually when recreating volume.

Hi, Can you send the volume info, and volume status output and the tier logs. And I need to know the size of the files that are being stored.
