Well, went forward with the messing :-)
I killed a node and added new bigger node of 10G.
The recovery has been fast.

Without rebooting the guest I tried to write a small amount of data by dd
dd if=/dev/zero of=/mnt/sda1/smallfile bs=1M count=128 but
but I had to stop it because it was very slow.
I tried to poweroff the guest but i hanged up, so I had to kill it.
After the reboot, it was not possible to mount sda1
'/dev/sda1 can't read superblock'.
I tried then
xfs_repair -L /dev/sda1
xfs_repair: pwrite64 failed: Input/output error
<repeated severl times>
dmesg is showing I/O errors
Dec 13 11:59:05 [io 7284] prealloc(303) failed to preallocate space,
No space left on device
Dec 13 11:59:05 [io 7284] err_to_sderr(129) diskfull, oid=7c2b25000002f1
<repeated several times>
After that I was able to mount sda1.
I tried to run dd again with small data amount but this time I was not
even able to stop it.
I had to kill the guest. Note: before write anything, I removed all
file from /mnt/sda1.
I', trying now to check the disk consistency
