IBM Tivoli Storage Manager for Space Management for UNIX: User's Guide


Appendix B. The .SpaceMan Directory

Tivoli Storage Manager creates file system-specific control files that reside in a hidden directory named .SpaceMan on each file system to which you add space management. These files also reside in the /etc/adsm/SpaceMan directory that Tivoli Storage Manager creates when you install the HSM client. The HSM client automatically excludes these files from space management. User action is not required to ensure that the files remain on your local file systems. Table 20 describes the file contents of this directory.

Table 20. HSM Control Files

File Name Description
config/dsmmigfstab File containing space-managed file system names and the space management settings that you selected for each file system.
config/dsmmigfstab.pid A lock file for the dsmmigfstab file.
config/dmiFSGlobalState Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file systems only.

Global and HSM-managed file system information. Related to the DMAPI interface.

config/dmiFSGlobalState.pid A lock file for the dmiFSGlobalState file.
ActiveRecallTab Active recall table.

Space Management Objects

When you add space management to your file systems, the HSM client creates control files in a hidden directory named .SpaceMan. Table 21 provides a brief description of objects that are stored in the .SpaceMan directory in each file system to which you add space management. The HSM client requires these objects for processing.

Attention: The HSM client can create other objects in the .SpaceMan directory during space management processing. Do not delete or modify the .SpaceMan directory, its contents, or any of the file ownerships and permissions.

Table 21. Control Files Stored in the .SpaceMan Directory

Files Description
orphan.stubs Records the names of any files for which a stub file exists on your local file system, but a corresponding migrated file does not exist in Tivoli Storage Manager storage.
status Records space management-related statistics for your file system.
premigrdb.dir
premigrdb.pag
Valid for AIX JFS file systems only

Stores the premigrated files database that contains information about each premigrated file.

dmiFSState Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file systems only

Stores information about the file system.

logdir/ Records information during file migration or recall. It uses this information to complete any interrupted transactions, such as a system failure.
SDR/ Valid for AIX (IBM Regatta pSeries 690)

Stores information for failover that must be shared between cluster nodes that are configured as failover nodes. The directory exists in only one of the .SpaceMan directories of HSM-managed file systems.

reserved/ Valid for AIX GPFS, Linux86 GPFS, Solaris VxFS, and HP-UX VxFS file systems only

Contains reserved files for demand migration.
