Same here, Now mounting cephfs hangs for a minute then says "mount error 5 = Input/output error" Since the new pool has id=3, I've also executed "ceph mds add_data_pool 3" and "ceph mds remove_data_pool 0" The monitor log has this line: 2013-03-15 16:08:08.327049 7fe957441700 0 -- 192.168.21.11:6789/0 >> 192.168.21.10:0/491826119 pipe(0x1b94c80 sd=23 :6789 s=0 pgs=0 cs=0 l=0).accept peer addr is really 192.168.21.10:0/491826119 (socket is 192.168.21.10:54670/0) -- Marco Aroldi 2013/3/15 Dan van der Ster <dan@xxxxxxxxxxxxxx>: > Hi, > > > On Fri, Mar 15, 2013 at 9:52 AM, Sebastien Han <sebastien.han@xxxxxxxxxxxx> > wrote: >> >> Hi, >> >> It's not recommended to use this command yet. >> >> As a workaround you can do: >> >> $ ceph osd pool create <my-new-pool> <pg_num> >> $ rados cppool <my-old-pool> <my-new-pool> >> $ ceph osd pool delete <my-old-pool> >> $ ceph osd pool rename <my-new-pool> <my-old-pool> > > > > We've just done exactly this on the default pool data, and it leaves cephfs > mounts in a hanging state.
