“Include snapshots” made NFS shares from ZFS appliance shrinking

January 17th, 2014

Today I met one weird issue when checking one NFS share mounted from ZFS appliance. The NFS filesystem mounted on client was shrinking when I removed files as the space on that filesystem was getting low. But what made me confused was that the filesystem's size would getting lower! Shouldn't the free space getting larger and the size keep unchanged?

After some debugging, I found that this was caused by ZFS appliance shares' "Include snapshots". When I uncheck "Include snapshots", the issue was gone!

Good Luck!
