Hi list!
I have installed two nodes cluster with kvm vms and drbd storage in
primary/primary mode. Kvm images stored directly on drbd device in raw
format is successfully synced between two nodes:
# cat /proc/drbd
version: 8.3.13 (api:88/proto:86-96)
GIT-hash: 83ca112086600faacab2f157bc5a9324f7bd7f77 build by
root@sighted, 2012-10-09 12:47:51
0: cs:Connected ro:Primary/Primary ds:UpToDate/UpToDate C r-----
ns:56570743 nr:12684 dw:56092323 dr:2746853 al:24086 bm:108 lo:0
pe:1 ua:0 ap:1 ep:1 wo:b oos:0
Then I decided to create new replicated logical device to store my
backups. To do this I do:
lvcreate --name ovz-storage --size 1.2T drbdvg
mkfs.ext3 /dev/drbdvg/ovz-storage
cd /var/lib/vz
mkdir ovz-storage
mount /dev/drbdvg/ovz-storage /var/lib/vz/ovz-storage
mount /var/lib/vz/ovz-storage
But when I added any data in mounted directory
(/var/lib/vz/ovz-storage), they doesn't replicated to another node.
Output from console of two nodes:
# lvs
LV VG Attr LSize Pool Origin Data% Move Log
Copy% Convert
ovz-storage drbdvg -wi-ao-- 1.20t
vm-100-disk-1 drbdvg -wi-a--- 10.00g
vm-102-disk-1 drbdvg -wi-ao-- 5.00g
vm-107-disk-1 drbdvg -wi-ao-- 4.00g
data pve -wi-ao-- 3.51t
root pve -wi-ao-- 96.00g
swap pve -wi-ao-- 15.00g
# mount
...
/dev/mapper/drbdvg-ovz--storage on /var/lib/vz/ovz-storage type ext3
(rw,_netdev)
How to troubleshoot this problem? Any help would be appreciated!
