- _x_f_s__f_r_e_e_z_e suspends and resumes access to an XFS filesystem.
-
- _x_f_s__f_r_e_e_z_e halts new access to the filesystem and creates a stable image
- on disk. _x_f_s__f_r_e_e_z_e is intended to be used with volume managers and
- hardware RAID devices that support the creation of snapshots.
-
- The _m_o_u_n_t-_p_o_i_n_t argument is the pathname of the directory where the
- filesystem is mounted. The filesystem must be mounted to be frozen and
- can not be the root filesystem.
-
- The ----ffff flag requests the specified XFS filesystem to be frozen from new
- modifications. When this is selected, all ongoing transactions 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 attemting
- to write to the frozen filesystem will be blocked waiting for the
- filessytem to be unfrozen.
-
- Note that even after freezing, some files may still be in the process of
- being unlinked. These files are noted in the disk image and the
- unlinking will be completed after the filesystem is unfrozen or a
- mmmmoooouuuunnnntttt(1m) of the snapshot is done.
-
- The ----uuuu option is used to unfreeze the filesystem and allow operations to
- continue. Any filesystem modifications that were blocked by the freeze
- are unblocked and allowed to complete.
-
- One of ----ffff or ----uuuu must be supplied to xxxxffffssss____ffffrrrreeeeeeeezzzzeeee.
