check-disk.pl

Verify the filesystem on some virtual disk.

This command validates and repairs the filesystem on a virtual disk, using the fsck command. The system the disk is on is set with the --host flag, and the disk to check be specified by real filename using --real or virtual device with --virt.

This can be useful if a system is failing to boot fully, and getting stuck in the "Ping failed" state. Often the cause is a un-clean shutdown that has left a virtual disk with an invalid filesystem. This API command can correct those kinds of errors (after the system is shut down).
