Doc Text: |
When a volume is down and there is an attempt to access .snaps directory, a negative cache entry is created in the Kernal Virtual File System(VFS) cache for .snaps.
After the volume is brought back online accessing .snaps still fails with an ENOENT error because of the negative cache entry.
Workaround:
Clear the kernel VFS cache by executing the following command:
# echo 3 >/proc/sys/vm/drop_caches
