man xfsinvutil (Administration système) - xfsdump inventory database checking and pruning utility

NAME

xfsinvutil - xfsdump inventory database checking and pruning utility

SYNOPSIS

xfsinvutil [-F|-i] [-u UUID] [-M mount_point]
		 [-m media_label] mm/dd/yyyy
xfsinvutil -i
xfsinvutil -C

DESCRIPTION

xfsdump maintains an online dump inventory in /var/lib/xfsdump/inventory. The -I option of xfsdump displays the inventory contents hierarchically. The levels of the hierarchy are: filesystem, dump session, stream, and media file.

Over time, this database may grow too large as xfsdump (8) and xfsrestore(8) do not remove entries from the inventory. The database may also develop inconsistencies for various reasons such as operator errors etc., that may cause xfsdump or xfsrestore to print error or warning messages.

xfsinvutil is an utility to check this inventory database for consistency, to remove entries of dump sessions which may no longer be of relevance, and to browse the contents of the inventory.

xfsinvutil may be used in three different modes. In the first mode xfsinvutil steps over each dump session recorded in the inventory and prompts for a yes or no response to whether each session should be pruned. The second is a batch mode in which xfsinvutil will prune every entry matching the supplied criteria. The third mode allows the user to browse the inventory in detail, to delete or undelete records at will and also to import inventories from other hosts.

The following command line options are available:

-F
Don't prompt the operator. When xfsinvutil encounters a matching dump session, xfsinvutil will normally ask the operator for permission to delete the entry. With this option the deletion is performed, no questions asked.
-i
Interactive mode. Causes xfsinvutil to run in a mode that will allow the operator to browse the contents of the inventory. Please refer to the Interactive Mode section below for more information.
-M mount_point mm/dd/yyyy
Specifies the mount point and cut-off date of inventory entries to be selected for pruning. xfsinvutil prompts the operator when a dump session in the inventory is identified by the mount point and was created prior to the specified date. The operator can then select specific dump sessions for removal from the inventory database. This prompt will not happen if the -n option is used; it will be assumed that the pruning is wanted. xfsinvutil also performs consistency checks on other inventory database entries when invoked with this option.

The mountpoint must match the mount point as specified in the inventory shown using xfsdump with the -I option. This includes the host name and the mount path.

-u UUID
Specifies the filesystem universally unique identifier (UUID) of inventory entries to be selected for pruning. This option is equivalent to the -M option.
-m media_label
If specified, only sessions with at least one media file whose label matches this value will be eligible for pruning. This restriction is in addition to those imposed by the date and the -M or -u options. This option allows the pruning of all inventory references to media which may have been overwritten or lost.
-n
With this option, xfsinvutil will not ask any confirmation questions regarding sessions to prune. (It is the "Nike" option).
-C
With this option, xfsinvutil performs consistency checks for all entries in the inventory database. It fixes any problems found. If no consistent entries are found , the corresponding inventory database file is removed.

Interactive Mode

When run with -i, xfsinvutil will present the operator with a hierarchical representation of the xfsdump inventory. In this mode, the operator can use the arrow keys (or the h j k l keys) to navigate the inventory and also use the following keys and functionality:

+
Expand a branch of the tree.
-
Collapse a branch of the tree.
*
Fully expand a branch of the tree.
%
Fully collapse a branch of the tree.
h
Move selection to the parent entry.
l
Move selection to the child entry.
j
Move selection to next entry.
k
Move selection to previous entry.
d
Mark the current record, and all sub-records, to be deleted.
u
Clear the current record and all parent records from being deleted.
i
Import another xfsdump inventory.
?
Show help window.
x
Commit any changes made to the inventory, and exit the program.
q
Exit the program without committing any changes to the inventory.

Inventories from other hosts can be imported to create a larger common inventory. It is recommended that the contents of /var/lib/xfsdump/inventory on the remote host be copied to a temporary local directory prior to running xfsinvutil. When xfsinvutil is run in interactive mode, and the operator hits i, they will be prompted for the path to the inventory to be imported. xfsinvutil will then add the contents of the imported inventory to the main window, and all entries will be marked as imported. The operator can then delete any of these entries that are not to be imported. When the operator commits the changes, xfsinvutil will import any entries which were not marked as deleted. Deleted entries are not actually deleted from the original imported inventory.

NOTES

Inventory

Each dump session updates an inventory database in /var/lib/xfsdump/inventory. xfsdump uses the inventory to determine the base of incremental and resumed dumps.

This database can be displayed by invoking xfsdump with the -I option. The display uses tabbed indentation to present the inventory hierarchically. The first level is filesystem. The second level is session. The third level is media stream (currently only one stream is supported). The fourth level lists the media files sequentially composing the stream.
