NAME

chk_cyrus - Cyrus IMAP documentation

Perform a consistency check of the Cyrus IMAP mail spool.

SYNOPSIS

chk_cyrus [ -C config-file ] [ -P partition | -M mailbox ]

DESCRIPTION

chk_cyrus is used to perform a consistency check on the cyrus datastore, and output a list of files/directories that are expected to exist, but do not. Status messages are output to stderr, the list of files/directories is output to stdout. This list can be passed to a backup program to aid a partial restoration, for instance.

chk_cyrus reads its configuration options out of the imapd.conf(5) <#std-cyrusman-imapd.conf-5> file unless specified otherwise by -C.

OPTIONS

-C config-file: Use the specified configuration file config-file rather than the default imapd.conf(5) <#std-cyrusman-imapd.conf-5>.

-P partition, --partition=partition: Limit to partition partition. May not be specified with -M.

-M mailbox, --mailbox=mailbox: Only check mailbox mailbox. May not be specified with -P.
Important:

The mailbox must be specified in the internal format, so rather than specifying user/john/Trash@example.org, you will want to specify example.org!user.john.Trash.

EXAMPLES

chk_cyrus -P default

Perform consistency checks on default partition.

chk_cyrus -C /usr/local/etc/imapd-slot1.conf -P default

Perform consistency checks on default partition using specified configuration file.

chk_cyrus -M user.marysmith

Perform consistency checks on mailbox user.marysmith.
