NAME
shfragbf - displays frag file information SYNOPSIS
/sbin/advfs/shfragbf file_system /.tags/1 OPERANDS
Specifies the fileset mount point of the file system to display. DESCRIPTION
Use this command to display how much space is used on the frag file. Type The frag type is 0K (not in use), 1K for 1K frags, etc. Grps Specifies the number of groups of the frag type. bad Specifies the number of bad group headers of this type. Frags Specifies the number of fragments of this type. free Specifies the number of free frags of this type. in-use Specifies the number of fragments in use. Bytes Specifies the total bytes in this frag type. free Specifies the number of bytes free in this type. in-use Specifies the number of bytes in use in this type. RESTRICTIONS
You must have root user privileges to access this command. EXAMPLES
Following is an example of the shfragbf output: # shfragbf /usr/.tags/1 Type Grps bad Frags free in-use Bytes free in-use ---- ------ ------ ------ ------ ------ ------ ------ ------ 0k 0 0 0 0 0 0k 0k 0k 1k 10 0 1270 130 1140 1270k 130k 1140k 2k 11 0 693 54 639 1386k 108k 1278k 3k 20 0 840 39 801 2520k 117k 2403k 4k 19 0 589 22 567 2356k 88k 2268k 5k 16 0 400 5 395 2000k 25k 1975k 6k 17 0 357 6 351 2142k 36k 2106k 7k 21 0 378 9 369 2646k 63k 2583k Percent Free Frags per Group Histogram Type Grps 9% 19% 29% 39% 49% 59% 69% 79% 89% 99% 100% ---- ------ --- --- --- --- --- --- --- --- --- --- --- 0k 0 0 0 0 0 0 0 0 0 0 0 0 1k 10 8 0 1 0 0 0 0 0 0 0 0 2k 11 10 0 0 0 0 0 0 0 1 0 0 3k 20 19 0 0 0 0 0 0 0 1 0 0 4k 19 18 0 0 0 0 0 1 0 0 0 0 5k 16 15 0 1 0 0 0 0 0 0 0 0 6k 17 16 0 1 0 0 0 0 0 0 0 0 7k 21 20 0 0 0 1 0 0 0 0 0 0 fragbf occupies 14592k bytes 13753k in-use, 567k free, 114k overhead, 158k wasted FILES

tag2name(8)						      System Manager's Manual						       tag2name(8)

NAME
tag2name - Display the path name of an AdvFS file SYNOPSIS
/sbin/advfs/tag2name tags_directory/file_tag /sbin/advfs/tag2name [-r] domain fileset_id file_tag OPTIONS
Specify the [-r] option to operate on the raw device (character device special file) of the fileset instead of the block device. OPERANDS
Specifies the name of an AdvFS domain. Specifies the name of an AdvFS fileset using the following format: Specify the -S tag to force the command to interpret the name you supply as a fileset name. Specify the fileset by entering either the name of the fileset, fileset, or the file's fileset tag number, -T fileset_tag. Specifies the relative path of the AdvFS tags directory for a fileset. If you do not spec- ify this directory, the default is mount_point/.tags. Specifies an AdvFS file tag number. DESCRIPTION
Internally, AdvFS identifies files by tag numbers (similar to inodes in UFS). Internal messages, error messages, and output from diagnostic utilities usually specify a tag number in place of a file name. Use the tag2name command to determine the name and path of an AdvFS file that is identified by a tag number. If you enter an invalid tag number, the command returns the range of the valid tags for the fileset. Mounted Filesets Each mounted AdvFS fileset has a directory in its mount point. To obtain a file name, specify the path to the directory for the fileset, followed by the tag number. The full path name of the corresponding file is displayed to stdout. This syntax uses AdvFS system calls. Unmounted Filesets When you use the second form, the utility does not use AdvFS code and does not depend on the filset being mounted. The path name of the file is relative to the fileset and is displayed on stdout. One use of the second form is to obtain names of files from a fileset that is unmounted and might produce a domain panic or a system panic if it were mounted. NOTES
An active domain, which is a domain with one or more of its filesets mounted, has all of its volumes opened using block device special files. These devices cannot be opened a second time without first being unmounted. However, the character device special files for the volumes can be opened more than once while still mounted. It can be misleading to use the second form of this utility on a domain with mounted filesets. Unlike the first form of the utility, the second form does not synchronize its read requests with AdvFS file domain read and write requests. To avoid this problem, unmount all the active filesets in the domain before using the second form of this utility. For example, the AdvFS can be writing to the disk as the utility is reading from the disk. Therefore, when you run the utility, metadata may not have been flushed in time for the utility to read it and consecutive reads of the same file page may return unpredictable or con- tradictory results. [The domain is not harmed.] RESTRICTIONS
The second form of this utility can fail to open a block device, even when there are no filesets mounted for the domain and the AdvFS dae- mon, advfsd is running. The daemon, as it runs, activates the domain for a brief time. If the tag2name utility fails in this situation, run it again. You must be the root user to use the tag2name utility. The tag you specify must be numeric and greater than 1. EXAMPLES
The following example displays the file name corresponding to tag 5 in the usr fileset. It assumes the current working directory is /usr: # /sbin/advfs/tag2name .tags/5 /usr/quota.group The following example displays the file name of the file whose tag is 145 in domain_1 fileset_1: # /sbin/advfs/tag2name domain_1 fileset_1 145 joe/save/oldfile FILES
Specifies the command path. Specifies the volumes in the domain. SEE ALSO
