savemeta(8)savemeta(8)NAMEsavemeta - Takes a snapshot of an AdvFS domain's metadata
SYNOPSIS
/sbin/advfs/savemeta [-LSTtr] [-f fileset] domain savedir
OPTIONS
Saves the structure information from the frag file in each named file‐
set to the savedir. If this option is not specified, the default is to
write no frag file information to the savedir. Do not save the
domain's log file to the savedir. If this option is not specified, the
default is to write the log file to the savedir. Allows savemeta to
run on mounted but corrupt domains by acquiring metadata information
from the raw device. Do not save each volume's storage bitmap (SBM) to
the savedir. If this option is not specified, the default is to write
each volume's SBM to the savedir. Do not save the domain's root tag
file to the savedir. If this option is not specified, the default is
to write the root tag file to the savedir. Do not save the fileset tag
files to the savedir. If this option is not specified, the default is
to write the fileset tag files to the savedir.
OPERANDS
The name of the AdvFS domain from which you want to obtain the meta‐
data. The name of a directory into which the saved metadata is to be
written.
DESCRIPTION
This script saves a snapshot of the specified domain metadata into a
directory, savedir, that has the following structure:
savedir/volume_directory/RBMT_file
/BMT_file
/SBM_file
/log_file
/tag_file
/fileset_directory/frag_file
/tag_file
By default, the savemeta command saves all the bitfile metadata (BMT),
all the SBM, the log and root tag files, and the fileset tag files. If
you specify the -f option, the command saves the frag file information
for each fileset.
Caution
When the -r option is supplied and a fileset is mounted, the raw disk
being read may not have all the data that is in the kernel's buffers.
When this happens the data saved by savemeta may be inconsistent.
RESTRICTIONS
You must be the root user to use this command.
EXIT STATUS
This command returns a 0 (zero) on success. Otherwise, it returns a 1
and displays an error diagnostic.
FILES
The command path.
