fsfreeze

FSFREEZE(8)						       System Administration						       FSFREEZE(8)

NAME

       fsfreeze - suspend access to a filesystem (Linux Ext3/4, ReiserFS, JFS, XFS)

SYNOPSIS

       fsfreeze -f mountpoint

       fsfreeze -u mountpoint

DESCRIPTION

       fsfreeze suspends and resumes access to an filesystem

       fsfreeze halts new access to the filesystem and creates a stable image on disk.	fsfreeze is intended to be used with hardware RAID devices
       that support the creation of snapshots.

       fsfreeze is unnecessary for device-mapper devices. The device-mapper (and LVM) automatically freezes filesystem on the device when a  snap-
       shot creation is requested.  For more details see the dmsetup(8) man page.

       The  mount-point  argument  is  the pathname of the directory where the filesystem is mounted.  The filesystem must be mounted to be frozen
       (see mount(8)).

OPTIONS

       -h, --help
	      Print help and exit.

       -f, --freeze
	      This option requests the specified a filesystem to be frozen from new modifications.  When this is selected,  all  ongoing  transac-
	      tions  in  the  filesystem  are  allowed to complete, new write system calls are halted, other calls which modify the filesystem are
	      halted, and all dirty data, metadata, and log information are written to disk.  Any  process  attempting	to  write  to  the  frozen
	      filesystem will block waiting for the filesystem to be unfrozen.

	      Note  that  even after freezing, the on-disk filesystem can contain information on files that are still in the process of unlinking.
	      These files will not be unlinked until the filesystem is unfrozen or a clean mount of the snapshot is complete.

       -u, --unfreeze
	      This option is used to un-freeze the filesystem and allow operations to continue.  Any filesystem modifications that were blocked by
	      the freeze are unblocked and allowed to complete.

NOTES

       This man page based on xfs_freeze.  One of -f or -u must be supplied to fsfreeze.
