[Ocfs2-users] error messages in syslog with reflink

[Lentes, Bernd]

Hi,

we have a two node cluster running. Resources are virtual machines, their harddisk images reside on an ocfs2 partition.
Each night at 10:30 pm the virtual machines are shut down, a snapshot is taken, they are immediately started again and the snapshot is zipped to a CIFS share.
In the log of the node i find:

 ...
2020-07-15T22:32:11.062144+02:00 ha-idg-2 kernel: [1408734.851910] (reflink,26023,16):ocfs2_reflink_ioctl:4431 ERROR: status = -17

 ...

That's the time when the snapshot is taken.
The snapshot is taken via: $REFLINK_BIN -f ${GUESTS[z]}.raw $REFLINK_PATH >> $LOGFILE 2>&1
$REFLINK_BIN is /usr/bin/reflink
What does it mean ? Is it a severe problem ?

Thanks.


Bernd
