August 10, 20196 yr This morning I decided to remove two drives from my cache pool. The cache pool consisted of 1Tb+500Gb+500Gb drives for a total of 1Tb. As a result of removing the two 500Gb drives the 1Tb is now un-mountable. Is there any option to recover data from the 1Tb or the two 500Gb drives? Reading the forums -after the fact- only one drive can be removed from the pool at a time and then rebalance before removing the second. I will try to put the two 500Gb back but in case this doesn't work I wanted to see if there are any options. Thank you.
August 11, 20196 yr There isn't. RAID1 only allows you to lose up to half of your disks. Losing 2 in a 3-disk RAID 1 = more than half = lost data.
August 11, 20196 yr Author Thanks, luckily I had a one week old backup for the data stored on the cache drive - up and running now.
