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.
