savemeta(8) System Manager's Manual savemeta(8) NAME
savemeta - Takes a snapshot of an AdvFS domain's metadata SYNOPSIS
/sbin/advfs/savemeta [-LSTt] [-f fileset] domain savedir OPTIONS
Saves the structure information from the frag file in each named fileset 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. 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 file domain from which you want to obtain the metadata. 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. 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. SEE ALSO

vdf(8) System Manager's Manual vdf(8) NAME
vdf - Display disk information for AdvFS domains and filesets SYNOPSIS
/sbin/advfs/vdf [-k] [-l] domain | domain#fileset OPTIONS
Display disk blocks as 1024-byte blocks instead of the default of 512-byte blocks. When the -l option is specified, the default informa- tion for both the domain and filesets is reformatted to show the relationships between them. For example, any domain metadata displayed is the total metadata shared by filesets in the domain. OPERANDS
The full path name of an AdvFS file domain. When a domain argument is specified, the default display contains information about the number of disk blocks allocated to the domain, the number of disk blocks in use by the domain, and the number of disk blocks that are available to the domain. The name of an AdvFS fileset in an AdvFS file domain. When a domain#fileset argument is specified, the default display contains information about the number of disk blocks allocated to the fileset, the number of disk blocks in use by the fileset, and the number of disk blocks that are available to the fileset. This information is in the same format as that displayed by the df command. DESCRIPTION
The vdf utility is a script that reformats output from the showfdmn, showfsets, shfragbf, and df utilities in order to display information about the disk usage of AdvFS file domains and filesets. In addition, the utility computes and displays the sizes of metadata files in a domain or fileset. NOTES
The disk space used by clone filesets is not calculated. If clone filesets are present in the specified domain, the utility displays the following warning message: Clone fileset(s) in this domain; totals may not be accurate RESTRICTIONS
You must be the root user to use this command. The command cannot be used on filesets that are NFS mounted. All filesets in a domain must be mounted in order to calculate the disk usage of the domain. EXIT STATUS
The utility returns a value of 0 (zero) on successful completion. It returns a value of 1 on failure. EXAMPLES
The following example shows the summary information for a fileset named testfs in a domain named test. The output is the same as for the df command: # vdf test#testfs Filesystem 512-blocks Used Available Capacity Mounted on test#testfs 60000 20800 39200 35% /mnt The following example shows the summary information for a domain named usr_domain where the number of blocks used for meta- data and data equal 89% of the domain's capacity: # vdf usr_domain Domain 512-blocks Metadata Used Available Capacity usr_domain 65536 11219 47549 6768 89% The following example shows a detailed display of the domain that contains the fileset test#testfs. There are two filesets in the domain; each has a quota limit of 60,000 blocks: # vdf -l test#testfs Domain 512-blocks Metadata Used Available Capacity test 266240 5824 29128 231288 13% Fileset QuotaLimit Used Available Capacity testfs 60000 20800 39200 35% testfs2 60000 8328 51672 14% The following example shows a detailed display of a fileset that is the only fileset in the domain and that the fileset has a quota limit that is greater than the domain can hold: # vdf -l test#testfs Domain 512-blocks Metadata Used Avail- able Capacity test 266240 5824 29128 231288 13% Fileset QuotaLimit Used Available Capacity testfs 300000 20800 231288 8% FILES
