LCTL-SNAPSHOT_MODIFY(8)

NAME
lctl-snapshot_modify - modify Lustre snapshot

SYNOPSIS

lctl snapshot_modify [-c | --comment comment] {-F | --fsname fsname}
                  [-h | --help] {-n | --name ssname} [-N | --new new_ssname]
                  [-r | --rsh remote_shell]

DESCRIPTION
Modify the specified snapshot. The tool loads system configuration from the file /etc/ldev.conf as described in the lctl(8) SNAPSHOT section. Then, the snapshot pieces are modified on every Lustre target (MGT/MDT/OST).

OPTIONS

-c, --comment comment
    Add comment (if it had not been specified with snapshot_create) or change the comment for the given snapshot.

-F, --fsname fsname
    The filesystem name.

-h, --help
    For help information.

-n, --name ssname
    The snapshot (to be modified) name must be specified.

-N, --new new_ssname
    Rename the snapshot to the new name. It follows the general ZFS snapshot name rules, such as the max length is 256 bytes, cannot conflict with the reserved names, and so on.

-r, --rsh remote_shell
    Specify a shell to communicate with remote targets. The default value is ssh. It is the system admin's duty to guarantee that the specified remote_shell works well among targets without password authentication.

AVAILABILITY
lctl-snapshot-modify is part of the lustre(7) filesystem package.
