I created a ZFS pool on Ubuntu 14.04 without specifiying RAID or redundancy options, wrote some data to it, rebooted the machine and the pool is no longer available (UNAVAIL). I don't have the exact error to hand but it mentioned that there was not sufficient replication available. I created two datastores in the pool which consists of 2 3TB disks. ZFS was recommended to me for its deduplication abilities and I'm not concerned with redundancy at this point.
I actually only want RAID0 so no mirroring or redundancy in the short term. Is there a way to do this with ZFS or would I be better off with LVM?
zpool status -v:
sudo zpool status -v
pool: cryptoporticus
state: UNAVAIL
status: One or more devices could not be used because the label is missing
or invalid. There are insufficient replicas for the pool to continue
functioning.
action: Destroy and re-create the pool from
a backup source.
see: http://zfsonlinux.org/msg/ZFS-8000-5E
scan: none requested
config:
NAME STATE READ WRITE CKSUM
cryptoporticus UNAVAIL 0 0 0 insufficient replicas
sda ONLINE 0 0 0
sdc UNAVAIL 0 0 0
UPDATE
zpool export cyrptoporticus,
then zpool import cryptoporticus
resolved this for now. Is this likely to happen again on reboot?
