I am running out of space... Damnit!

I need to buy 8 more 6TB drives to expand my backup pool to all 4TB drives and my production pool with 6TB drives... It has been a good run for the last few years. I knew this day would come but it still sucks.

What % full is it "safe" to run a backup pool to? It only gets written to for replication tasks and Rsync on a schedule. Typically, the backup pool is never read from.

Thanks,

i believe the only hit is speed - my two pools are 95% with no problems.

obviously don't get 100% or you can't delete files

90% is where performance tanks. I personally wouldn't try going that far. @ethereal you're playing with fire, I hope you have good backups.

i am expanding a pool as we speak

going from 6 Tb to 16 Tb - i had 4 x 3 Tb RaidZ2 - will have 4 x 8 Tb by christmas.

i do also have backup on another pool - also on external hdd in a safe and bluray discs.

I hope to start buying drives soon. Should be able to get stuff upgraded before I get to 90%. Another option would be to delete some old shit... :)

My pool is at 73% currently so an expansion is in my future as well. I'm thinking about starting to purchase some 8TB WD mybooks and shuck them for my pool expansion. They're $160 at amazon right now, not a bad price.

I started buying HGST 6TB drives. I have to wait for them to go on sale again and pick up a few more. The 7200RPM HGSTs run about 6C hotter than my Seagate 5400RPM drives though. Supposed to be good drives though.

Cheers,
