Solaris ZFS Administration Guide

Importing Alternate Root Pools

Pools can also be imported using an alternate root. This feature allows for recovery situations, where the mount points should not be interpreted in context of the current root, but under some temporary directory where repairs can be performed. This feature also can be used when mounting removable media as described above.

In the following example, a pool called morpheus is imported with /mnt as the alternate root path. This example assumes that morpheus was previously exported.


# zpool import -R /a pool
# zpool list morpheus
NAME   SIZE   USED  AVAIL    CAP  HEALTH  ALTROOT
pool  44.8G    78K  44.7G     0%  ONLINE  /a
# zfs list pool
NAME   USED  AVAIL  REFER  MOUNTPOINT
pool  73.5K  44.1G    21K  /a/pool
