After applying the patch, the disk device ID has been changed, so the status of zfs pool snapshot is faulted. [root@r710 by-id]# zpool list NAME       SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT snapshot      -      -      -      -      -  FAULTED  - storage   27.2T  10.1T  17.1T    37%  1.00x  ONLINE  - Changing the /dev/ names on an existing pool can be done by simply exporting the pool and re-importing it with the -d option to specify which new names should be used. For example, to use the custom names in /dev/disk/by-vdev: #zpool export snapshot #zpool import -d /dev/disk/by-vdev snapshot

Usually, the /dev/disk/by-uuid does not show all disk's UUID. For example: [root@r710 ~]# ls -l /dev/disk/by-uuid total 0 lrwxrwxrwx 1 root root 10 Aug  3 15:45 0d97a78f-8a2c-4040-9ee4-6ed3764cd809 -> .        ./../sda3 lrwxrwxrwx 1 root root 10 Aug  3 15:45 54242d33-f140-4ffa-96a5-7cfac64bdb09 -> .        ./../sda1 lrwxrwxrwx 1 root root 10 Aug  3 15:45 bbdcaa28-a4de-47a4-804c-79e83fa31980 -> .        ./../sda2 blkid will show all of them including ZFS's dataset [root@r710 ~]# blkid /dev/sda2: UUID="bbdcaa28-a4de-47a4-804c-79e83fa31980" TYPE="ext4" /dev/sda1: UUID="54242d33-f140-4ffa-96a5-7cfac64bdb09" TYPE="ext4" /dev/sda3: UUID="0d97a78f-8a2c-4040-9ee4-6ed3764cd809" TYPE="swap" /dev/sda4: LABEL="snapshot" UUID="7237582886734482444" UUID_SUB="5054151785144376043" TYPE="zfs_member" /dev/sdb: LABEL="storage" UUID="6125443995338521040" UUID_SUB=...
