Hello all. I just noticed a really inexplicable (for me) behaviour: root@str957-cluster:/scratch/.resv2# mkdir test root@str957-cluster:/scratch/.resv2# ls -la total 4 drwxr-xr-x 16 root root 4096 Apr 22 11:40 .. root@str957-cluster:/scratch/.resv2# mkdir test mkdir: cannot create directory 'test': File exists root@str957-cluster:/scratch/.resv2# ls -la total 4 drwxr-xr-x 16 root root 4096 Apr 22 11:40 .. root@str957-cluster:/scratch/.resv2# cd test root@str957-cluster:/scratch/.resv2/test# pwd /scratch/.resv2/test The directory both exists and doesn't exist at the same time??? The volume is: Volume Name: cluster_data Type: Distributed-Replicate Volume ID: a8caaa90-d161-45bb-a68c-278263a8531a Status: Started Snapshot Count: 0 Number of Bricks: 21 x (2 + 1) = 63 Transport-type: tcp Bricks: Brick1: clustor00:/srv/bricks/00/d Brick2: clustor01:/srv/bricks/00/d Brick3: clustor02:/srv/quorum/00/d (arbiter) [...snip...] Brick61: clustor01:/srv/bricks/13/d Brick62: clustor02:/srv/bricks/13/d Brick63: clustor00:/srv/quorum/06/d (arbiter) Options Reconfigured: features.scrub: Active features.bitrot: on cluster.lookup-optimize: on performance.stat-prefetch: on performance.cache-refresh-timeout: 60 client.event-threads: 8 performance.client-io-threads: on nfs.disable: on transport.address-family: inet features.quota: on features.inode-quota: on features.quota-deem-statfs: on features.default-soft-limit: 90 cluster.self-heal-daemon: enable performance.write-behind-window-size: 128MB performance.parallel-readdir: on Disabling performance.parallel-readdir seems to "fix" it, but IIUC it shouldn't happen even with parallel-readdir turned on, right? PS: sometimes, access to the volume becomes quite slow (3-4s for a ls of a dozen files). Any hints about options I could enable or change? The 3 servers currently have only 96GB RAM (already asked to double it), and should host up to 36 bricks + 18 quorums). There are about 50 clients.
