vbmtchain(8) System Manager's Manual vbmtchain(8) NAME vbmtchain - displays mcells that describe metadata for a file SYNOPSIS /sbin/advfs/vbmtchain BMT_page cell special [special 2...] Specifies the page within the bitfile metadata table (BMT) of the vol- ume that contains the file's mcell. Specifies the cell of the BMT page that contains the file's mcell. Specifies the volume on which the file's primary mcell is located. Specifies the other volumes in this domain that may be accessed to follow the file's mcell chain. DESCRIPTION The vbmtchain utility displays metadata for a file. The file is de- scribed by the location of its primary mcell. Each mcell location is composed of three parts: volume, page within the BMT file located on that volume, and cell within the BMT page. The primary mcell for the root tag directory is found in the BMT of the volume containing the log. To find this volume for a domain, use the showfdmn or the advscan command. The volume marked "L" contains the log. Certain metadata files are in fixed locations: tab(@); lfHB lfHB lfHB lfHB l l l l. _ @Page@Cell@Volume _ Bitfile metadata table@0@0@every volume Storage bitmap@0@1@every volume Root tag directory@0@2@volume with log Transaction log file@0@3@volume with log _ The vbmtchain utility displays the attributes of the file including the time stamp, the extent map, and whether the file is a user directory or a data file.
