Version-Release number of selected component (if applicable): 3.7.3 This issue is resolved after changing the ulimit -n value from 1024 to 4096. If the brick count is more than 1024, we need to modify the ulimit -n value on clients as well as cluster nodes. So we can close this ticket. Closing as per comment-2 |
Created attachment 1076872 [details] log from client point Description of problem: when new bricks added to a existing running cluster, client1 (fuse) not able to list file and log throws error but same file able to list after remount and now again some other file is not listing. but able to list files in another client2 (fuse) when client1 is not bale to list file. Version-Release number of selected component (if applicable): How reproducible: random Steps to Reproduce: 1.20 node with each 36 bricks 2.create disperse vol with 8 + 2 adding node{1..10}:/brick1 node{1..10}:/brick2 likewise 3.create folder hierarchy like this. /root1/subroot1/aaaa/{a..z}/par{1..500}/chil{1..3} /root1/subroot1/bbbb/{a..z}/par{1..500}/chil{1..3} /root1/subroot2/aaaa/{a..z}/par{1..500}/chil{1..3} /root1/subroot2/bbbb/{a..z}/par{1..500}/chil{1..3} /root2/aaaa/{a..z}/par{1..500}/chil{1..3} /root3/aaaa/{a..z}/par{1..500}/chil{1..3} /root3/bbbb/{a..z}/par{1..500}/chil{1..3} /root3/bbbb/{a..z}/par{1..500}/chil{1..3} in child folder create 10 files in existing cluster add new bricks. add brick node{21..30}:/brick1 node{21..30}:/brick2 likewise but don't start rebalance or fix-layout now. also ensure in existing brick usage in cluster are above 80% so data will start to move to new bricks. start a transfering data to volume, now files will be written to newly added bricks. now read files from any of the chil folders it would be missing. Actual results: randomly files are not listing Expected results: show list files without any issue Additional info:
