Re: [ceph-users] CephsFS client hangs if one of mount-used MDS goes offline

Yes, another MDS takes it over and even comes back, but client does not always "unfreeze". Weird, i see some different versions.. ceph versions {     "mon": {     "ceph version 13.2.6 (7b695f835b03642f85998b2ae7b6dd093d9fbce4) mimic (stable)": 2,     "ceph version 13.2.8

[ceph-users] CephsFS client hangs if one of mount-used MDS goes offline

2020-01-20 Thread Anton Aleksandrov
Hello community, We have very small ceph cluster of just 12 OSDs (1 per small server), 3 MDS (one active) and 1 cephFS client. CephFS client is running Centos7, kernel 3.10.0-957.27.2.el7.x86_64. We created 3 MDS servers for redundancy and we mount our filesystem by connecting to 3 of them.
