[ceph-users] mds crash loop - Server.cc: 7503: FAILED ceph_assert(in->first <= straydn->first)

Hi all, We have a cephfs cluster in production for about 2 months and, for the past 2-3 weeks, we are regularly experiencing MDS crash loops (every 3-4 hours if we have some user activity). A temporary fix is to remove the MDSs in error (or unknown) state, stop samba & nfs-ganesha gateways

[ceph-users] Re: Use of an EC pool for the default data pool is discouraged

Hi Samuel, You have to use pool affinity. For example, with 3 pools in ceph pacific: - pool_fs_meta -> pool replicated, SSD only - pool_fs_data -> pool replicated, hdd only - pool_fs_data_ec -> pool EC, hdd #ceph fs new cephfsvol pool_fs_meta pool_fs_data #ceph osd pool set pool_fs_data_ec allo

[ceph-users] Re: are you using nfs-ganesha builds from download.ceph.com

Hi Dan, I probably have a very specific use of CEPH + nfs-ganesha but I don't use nfs-ganesha builds (from any location). The reason is that I had to patch nfs-ganesha 3.5 in order to play nicely with CEPHFS and POSIX ACLs (using VFS FSAL)... Arnaud ___

Hi all, I'm not sure to really understand how cephfs snapshots mirroring is supposing to work. I have 2 ceph clusters (pacific 16.2.4) and snapshots mirroring is set up for only one directory, /ec42/test, in our cephfs filesytem (it's for test purposes but we plan to use it with about 50-60

Hi, I just upgraded my cluster from 16.2.4 to 16.2.5 and I had an error during the upgrade of the first osd daemon (cf below). I fixed the error (I just created the missing directory on all hosts), then resume the upgrade. Now, everything is OK but I still have a warning:" [WRN] UPGRADE_REDEPL
