p4 storage
Display, verify, or update physical archive storage.
Syntax
p4 [g-opts] storage [-v [-q]] [-c change] [-T tags -F filters] [-m max] archive ... p4 [g-opts] storage -u [-c change] [-T tags -F filters] [-m max] archive ... p4 storage -d [-c change] [-y] [-D secs] [-t target] [-q] archive ... p4 storage -w p4 storage -U [-q] [-n threads] archive... p4 storage -l start|pause|restart|wait|status|cancel //depotDirectory/...
Description
A user with admin access can display information about the server archive files and their usage with
p4 storage [-v [-q]] [-c change] [-T tags -F filters] [-m max] archive...
The -l option provides a group of commands to locate orphaned archive files and mark them for removal by the storage -d command.
86400 seconds (24 hours) is the default delay before file removals, but you can change this. See -d under Options.
See also "Reclaiming disk space by removing orphaned archive files" under Managing disk space in the Helix Core Server Administrator Guide.
The fields that storage displays are:
lbrFile | the path of the archive file |
lbrRev | the revision of the archive file |
lbrType |
the file type of the archive file, such as text+C See File types. |
lbrRefCount | how many revisions refer to the archive file |
headTime | timestamp of when the record was written |
filesize | size of the revision contained in the archive file |
digest | MD5 digest of the revision contained in the archive file |
serverSize | Size of the archive file on the server at the time that revision was submitted or shelved |
compCksum | MD5 of the archive file containing the
revision on the server if the file is
compressed and submit.storagefields is 1 |
Additional fields when the -v flag is specified:
actualSize | actual size of revision contained in the archive file |
actualDigest | actual MD5 digest of revision contained in the archive file |
status | outcome of verify, OK, BAD or MISSING |
If upgrading from a version prior to 2019.1
If you are upgrading your Helix Core Server from a version prior to 2019.1 and your Perforce database has many keyed revisions, you might want to avoid the risk of delay incurred by calculating storage digest updates during the upgrade process. If so, consider using the -U option.
Options

Verifies that the specified archive files are intact. Computes and displays the digest of each archive.
p4 storage -v is similar to p4 verify except that:
|
||||||||||||||||||||||||||
|
Computes and saves the digest only for revisions that have no saved digest. |
||||||||||||||||||||||||||
|
Minimizes the output of the storage -v command, displaying only errors from mismatched digests or unreproducible revisions. |
||||||||||||||||||||||||||
-d |
Deletes unreferenced archives. The database row describing the archive is removed as well as the revision of the underlying archive if both of the following are true:
Without the -y as confirmation, the command merely lists the candidate files and revisions it would remove. With the -y as confirmation, files and revisions as well as zero referenced storage records are removed. Archives with a reference count of 0 are rare, but can be created by:
The listing of the candidate revisions can be suppressed with the -q option. |
||||||||||||||||||||||||||
-t target |
Filesystem target directory to which orphaned archive files are copied prior to deletion from the directory indicated by |
||||||||||||||||||||||||||
-c | Applies to the specified changelist. | ||||||||||||||||||||||||||
-T |
Applies to the specified tags, which can be specified using a comma- or space-delimited list. Example: -T "lbrFile, lbrRev" |
||||||||||||||||||||||||||
-F |
Applies to the specified filter. Lists only records satisfying the filter expression. This filter syntax is similar to the one used for jobs -e jobview and is used to evaluate the contents of the fields in the preceding list. Filtering is case-sensitive. Example: -v -F "lbrRefCount = 1 & status=OK" |
||||||||||||||||||||||||||
-m | Limits output to the specified number of records | ||||||||||||||||||||||||||
|
Provides a message that indicates when the upgrade process is complete by displaying "The storage upgrade process is complete". For details, see Helix Core Server Administrator Guide on upgrading to 2019.1 or later. |
||||||||||||||||||||||||||
-U [-q] [-n threads]
|
To avoid the delay incurred by calculating the digest during the upgrade, consider using the -U option after a storage upgrade has been performed with the lbr.storage.skipkeyed configurable set to skip keyword revisions. This option reads all the storage records. When it detects an unset digest field, it recomputes the digest and size fields, then updates the record. Invoking p4 storage -U -q -n threads suppresses progress messages. The |
||||||||||||||||||||||||||
-l
|
Allows the administrator to create, pause, restart and cancel background processes that can locate and mark orphan files. This process looks for files in the specified //depotDirectory and its subdirectories that match the naming convention for the server's archive file format. Each file that is found, along with its revision, is checked for a matching entry in the db.storage table. If no such entry is found, a new record is created that describes the file and revision combination with a reference count of 0. A later call to p4 storage -d will delete both those records with zero references and the associated the archive revision. p4 storage -l has subcommands:

Example of a possible workflow
Locating the orphaned files
To start the scan:
p4 storage -l start //depotDirectory/...
To get the status of the scan:
p4 storage -l status //depotDirectory/...
To pause the scan:
p4 storage -l pause //depotDirectory/...
To end the pause and resume the scan:
p4 storage -l restart //depotDirectory/...
To cancel the scan:
p4 storage -l cancel //depotDirectory/...
A scan remains in the system until it is canceled. To re-run a scan, first pause the scan (if it is active), then cancel the scan (even if it has completed or resulted in an error).
Reclaim disk space on the server
To save the orphaned files to your target directory and delete the zero references along with associated archive files from the depot directory specified:
p4 storage -d -y -t /myTargetDirectory //depotdirectory/...
where /myTargetDirectory is any operating system target directory, and, for Windows, might be something like D:\myCopyOfOrphanedFiles
