LCTL-SNAPSHOT_DESTROY(8)

NAME
lctl-snapshot_destroy - destroy Lustre snapshot

SYNOPSIS

lctl snapshot_destroy [-f | --force] {-F | --fsname fsname} [-h | --help]
                   {-n | --name ssname} [-r | --rsh remote_shell]

DESCRIPTION
Destroy 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 destroyed on every Lustre target (MGT/MDT/OST).

OPTIONS

-f, --force
    Destroy the specified snapshot by force. If the snapshot is mounted (see snapshot_mount), it will be umounted firstly, then destroyed. Even if some pieces of the snapshot are lost or broken for some reason(s), the remained parts of the snapshot still can be destroyed with this option specified.

-F, --fsname fsname
    The filesystem name.

-h, --help
    For help information.

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

-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-destroy is part of the lustre(7) filesystem package.
