Error description
When it is needed to remove log file system from a vSnap storage pool, e.g. due to a failing disk, the vsnap command could time out. The vSnap log will show: [time] INFO pid-7060 vsnap.cli CLI process started: ['pool', 'removelog', '--id', '1'] [time] INFO pid-7060 vsnap.zfs Updating pool id 1 to remove all log disks ... [time] ERROR pid-7060 vsnap.linux.system Timed out (480 seconds) waiting for command to complete: zpool remove vpool1 mirror-5 [time] INFO pid-7060 vsnap.linux.system Collecting process stacks in /opt/vsnap/log/stacks_hungproc_7074_1575102856.txt IBM Spectrum Protect Plus Versions Affected: IBM Spectrum Protect Plus 10.1.x and above Initial Impact: Medium Additional Keywords: SPP, SPPlus, TS003076677
Local fix
Run the underlying zpool command instead of the vsnap command. Determine the name of the log device to be removed: sudo zpool status Remove the log device: sudo zpool remove vpool1 mirror-1

Problem conclusion
Safely detaching a log or cache device from a vSnap pool can take several minutes especially if the pool is undergoing other I/O activity at the time of the removal. The vSnap CLI command for detaching a log/cache device did not wait long enough. It timed out too quickly and reported a failure even though the underlying removal was still in progress. The problem has been resolved by eliminating the redundant timeout mechanism at the CLI layer. The CLI now waits as long as necessary as long as the underlying removal is still in progress.
