Drush 5.9 - unable to untar

Question

Using the command:

 drush arr ~/drush-backups/site.tar.gz --db-url=mysql://df_database:password@localhost/df_databaseuser --destination=~/domains/site.kz/public_html/temp

(archive size is ~5gb),

I get this error:

 Unable to untar /home/user/drush-backups/site.tar.gz.                [error]
 Unable to extract site archive tarball to                            [error]
 /tmp/drush_tmp_1384866055_528b6107d88d6.

Why does it happen? However, when I try to untar archive lower than 1gb I'm not getting any errors.

Answer 1

By default the command drush archive-restore creates a unique temporary folder under /tmp (*/tmp/drush_tmp_1394487346_531e303223...*) where it will extract the archived tarball content, and later will move the $doc_root into the $destination - with the option overwrite.

I guess your /tmp folder resides on a separate partition, ~4GB in size; restoring a 3GB archive worked well, but it fails for 5BG. It looks like drush archive-restore works only when the system's temp folder is large enough to accommodate the extracted tarball.

PS. drush archive-restore is defined in archive.drush.inc :

function "drush_archive_restore" (drush_tarball_extract($file, $tmp)), where $tmp = drush_tempdir();

Funtion drush_tempdir() is defined in filesystem.inc - creates a unique temporary directory and returns its path. drush_tempdir() uses drush_find_tmp() which more likely returns /tmp

I got this exact error when I tried the following from a script:

drush arr ${DUMP_DIR}/`ls ./ | grep *.tar.gz` --destination=/home/foo/bar

with a single .tar.gz file in the directory. It turns out my filename was like: `some-file-MM-DD-YY-HH:MM:SS.tar.gz

in this case the : (colons) are not escaped by my shellscript and I get that generic extract error. Renaming my dump file to something simple like dump.tar.gz allows the drush command to complete.
