Unix network file lock

I am trying to run the "check" function of backup program "restic" on one of the backup repositories it's created. No matter what I do, it crashes due to a fatal "already locked" problem.

You should first use ps -fp to see if the process that locked the repository still exists. Since the lock is already h old according to the error message, the process might be hung, or it might be a stale lockfile if the process does not exist or seems completely unrelated. If the process with PID seems related, you might use lsof -p to see which files it has open.

With luck, one of those files might be a log file that might provide more information about the state of the process. If it seems safe to interrupt, you could use kill to try and stop it relatively nicely, allowing it a chance to clean up its lock file as it exits. If the process refuses to die with the kill command, you could use kill -9 to force it to stop, but in that case, you will definitely have to take further steps to clear the lock. According to issue in the GitHub page of restic , after killing the hung process, you might use this command to clear the stale lock:.

If the hung process was in the middle of some backup operation, you might need to perform these commands too:. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Note that Server for NFS supports transparent failover only when manually initiated, typically during planned maintenance. If an unplanned failover occurs, NFS clients lose their connections. This means that if a local app or SMB session attempts to access the same file that an NFS client is accessing immediately after a planned failover, the NFS client might lose its connections transparent failover wouldn't succeed.

Using the snap-in, you can manage the Server for NFS components installed on the computer. Server for NFS also contains several Windows command-line administration tools:. These cmdlets provide an easy way to automate NFS management tasks. Skip to main content. This browser is no longer supported. More Insider Sign Out. Sign In Register. Sign Out Sign In Register.
