So i recently started using my SSD pool i built on my ZFS NAS for VMWare data store

I logged into the ESX host today to find that all my data stores were offline. (They're all on the NAS). So i login to nas and i find the SSD pool offline. Stating 1 of 4 drives is missing. Reason pool is offline is not enough replicas.

I tried clearing the error on the pool, exporting and re importing pool as well. No luck.

format command output
10. c6t5001B44ED53292F5d0 <ATA-SanDisk SDSSDA24-00RL-223.57GB>
/scsi_vhci/disk@g5001b44ed53292f5

12. c6t5001B44F0A2053DFd0 <ATA-SanDisk SDSSDA24-00RL-223.57GB>
/scsi_vhci/disk@g5001b44f0a2053df

root@NAS:/root# zpool import SSD_Pool
cannot import 'SSD_Pool': one or more devices is currently unavailable

Curious if anyone who knows raidz and storage better then me can shed some light on why losing a single drive in raid1z caused me to loose the entire pool?

I'm working on restoring from backups right now. so save the lecture :p

How did you create the pool? Sounds a lot like you didn't make it RAID-Z given it's stating "not enough replicas". Given the error messages it sounds like everything's gone, time to restore from backups.

Get us the output of 'zpool status' or if you, for some reason, don't see the pool there, get us the output of 'zpool import'.
