SALVAGE.LOCK(5) AFS File Reference SALVAGE.LOCK(5)NAME
salvage.lock - Prevents multiple simultaneous salvage operations on a partition
DESCRIPTION
The salvage.lock file guarantees that only one Salvager (salvager process) runs at a time on a file server machine (the single process can
fork multiple subprocesses to salvage multiple partitions in parallel). As the Salvager initializes, it creates the empty (zero-length)
file in the /var/lib/openafs/local directory and invokes the flock system call on it. It removes the file when it completes the salvage
operation. Because the Salvager must lock the file to run, only one Salvager can run at a time.

SalvageLog - Traces Salvager operations
DESCRIPTION
The SalvageLog file records a trace of Salvager (salvager process) operations on the local machine and describes any error conditions it
encounters.
If the SalvageLog file does not already exist in the /var/log/openafs directory when the Salvager starts, the process creates it and writes
initial start-up messages to it. If there is an existing file, the Salvager renames is to SalvageLog.old, overwriting the existing
SalvageLog.old file if it exists.
When the Salvager is salvaging an entire file server, it creates a separate log file for each partition it starts salvaging. That file will
be named SalvageLog.job where job is a job number that will normally (but is not guaranteed to) correspond to the index of the partition
being salvaged. Once salvaging of all partitions is complete, the Salvager will accumulate all the partition-specific log files, append
them to SalvageLog, and then remove the partition-specific files.
The file is in ASCII format. Administrators listed in the /etc/openafs/server/UserList file can use the bos getlog command to display its
contents. Alternatively, log onto the file server machine and use a text editor or a file display command such as the UNIX cat command. By
default, the mode bits on the SalvageLog file grant the required "r" (read) permission to all users.
The Salvager records operations only as it completes them, and cannot recover from failures by reviewing the file. The log contents are
useful for administrative evaluation of process failures and other problems.
