Hello,

during VM instalation I needed add 300GB new disk and format as EXT3.  
Easy task, but ....
Used  striped mirror volume for that  - created by:
# gluster volume create 12KVM12SC4 replica 2 stripe 2 1kvm1-SAN:/p4/GFS1 
1kvm2-SAN:/p4/GFS1 2kvm1-SAN /p4/GFS1 2kvm2-SAN:/p4/GFS1 force
- added disk throught  oVisrt GUI
- VM# partprobe
- VM# fdisk - make one partition, type linux
- VM# mkfs.ext3 /dev/vdb1
it hangs after cca 30% of format

oVirt alert:
*VM has been paused due to a storage I/O error*

so I tried to copy some  data directly from hypervizor ( cca 80GB ) to 
default gluster-ovirt mountpoint ( 
/rhev/data-center/mnt/glusterSD/localhost:_12KVM12SC4 ) with no hangs.
The same whole operation on volume distribute replica type succesfully done.

Can anybody help me with it ??

Maybe continual error on /var/log/messages occure will get right view on 
it :
