Hi, all!
I erased the VG having snapshot LV related to gluster volumes
and then, I tried to restore volume;
1. vgcreate vg_cluster /dev/sdb
2. lvcreate --size=10G --type=thin-pool -n tp_cluster vg_cluster
3. lvcreate -V 5G --thinpool vg_cluster/tp_cluster -n test_vol vg_cluster
4. gluster v stop test_vol
5. getfattr -n trusted.glusterfs.volume-id /volume/test_vol ( in other node)
6. setfattr -n trusted.glusterfs.volume-id -v 0sKtUJWIIpTeKWZx+S5PyXtQ== /volume/test_vol (already mounted)
7. gluster v start test_vol
8. restart glusterd
9. lvcreate -s vg_cluster/test_vol --setactivationskip=n --name 6564c50651484d09a36b912962c573df_0
10. lvcreate -s vg_cluster/test_vol --setactivationskip=n --name ee8c32a1941e4aba91feab21fbcb3c6c_0
11. lvcreate -s vg_cluster/test_vol --setactivationskip=n --name bf93dc34233646128f0c5f84c3ac1f83_0
12. reboot
It works, but bricks for snapshot is not working.
