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:
...

...
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

Hello Lentes, From the kernel message, it looks reflink in kernel-space did not succeed. Could you reproduce this bug stably? e.g. use a script to trigger this problem. Second, please share your Linux kernel version, and related HA configurations. Thanks Gang On 7/23/2020 8:45 PM, Lentes, Bernd wrote:> Hi, > > we have a two node cluster running.
