[Gluster-users] remote operation failed. [{errno=6}, {error=No such device or address}
hi guys. I have a replica volume which is mounted via loopback and mounts a okey. -> $ mount | grep VMs 127.0.0.1:/VMsy on /00-VMsy type fuse.glusterfs (rw,relatime,user_id=0,group_id=0,allow_other,max_read=131072) However, when something begins to operate on this fuse mounted path, then errors show: ... The message "W [MSGID: 114031] [client-rpc-fops_v2.c:1881:client4_0_seek_cbk] 0-VMsy-client-0: remote operation failed. [{errno=6}, {error=No such device or address}]" repeated 163398 times between [2025-06-25 11:01:29.439813 +0000] and [2025-06-25 11:02:34.980956 +0000] ... This above is a result of simple 'cp' off the fuse mount to a separate filesystem. 'cp' gets stuck forever. However, one peer, out of there, does not suffer from this issue - this box works as expected, nicely. Now - this issue does not occur at all, on any of three boxes, if volume is mounted this way: 10.1.1.100,10.1.1.101,10.1.1.99:/VMsy All three peers/boxes are "virtually" identical, yet there is one more "oddity" on the peer which does _not_ fail with above error, namely: -> $ du -xh /00-VMsy//enc.vdb.back1.proxmox.qcow2 71G??? /00-VMsy//enc.vdb.back1.proxmox.qcow2 where other two: -> $ du -sh /00-VMsy//enc.vdb.back1.proxmox.qcow2 2.9G??? /00-VMsy//enc.vdb.back1.proxmox.qcow2 'df' also reports that way. 71G is virtual size of qcow2 file. I'd put aside for now - still an interesting question - mount any other way VS mount to 127.0.0.1 and ask: how to make "failing" boxes to behave like the box which is error-free? All thoughts are much appreciated.
