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. ------------------------------------------------------------------------------------------------------------------------------------------ ~]# glsuter snpshot status Brick Path : 192.225.3.35: /var/run/gluster/snaps/bf93dc34233646128f0c5f84c3ac1f83/brick1 Volume Group : vg_cluster Brick Running : No Brick PID : N/A Data Percentage : 0.22 LV Size : 5.00g Brick Path : 192.225.3.36: /var/run/gluster/snaps/bf93dc34233646128f0c5f84c3ac1f83/brick2 Volume Group : vg_cluster Brick Running : No Brick PID : N/A Data Percentage : 0.22 LV Size : 5.00g Brick Path : 192.225.3.37: /var/run/gluster/snaps/bf93dc34233646128f0c5f84c3ac1f83/brick3 Volume Group : vg_cluster Brick Running : No Brick PID : N/A Data Percentage : 0.22 LV Size : 5.00g Brick Path : 192.225.3.38: /var/run/gluster/snaps/bf93dc34233646128f0c5f84c3ac1f83/brick4 Volume Group : vg_cluster Brick Running : Tes Brick PID : N/A Data Percentage : 0.22 LV Size : 5.00g ~]# gluster snapshot deactivate t3_GMT-2017.05.15-08.01.37 Deactivating snap will make its data inaccessible.
