Hi, I just tried these two raidz2 setups with 36 disks: 3x 10+2, 4x 7+2. The result is a bit puzzling for me, because I get the same capacity, although one setup is using 6 drives for redundancy, the other is using 8: --- root@pt-storage2:~ # zpool create data raidz2 gpt/disk-00 gpt/disk-01 gpt/disk-02 gpt/disk-03 gpt/disk-04 gpt/disk-05 gpt/disk-06 gpt/disk-07 gpt/disk-08 gpt/disk-09 gpt/disk-10 gpt/disk-11 raidz2 gpt/disk-12 gpt/disk-13 gpt/disk-14 gpt/disk-15 gpt/disk-16 gpt/disk-17 gpt/disk-18 gpt/disk-19 gpt/disk-20 gpt/disk-21 gpt/disk-22 gpt/disk-23 raidz2 gpt/disk-24 gpt/disk-25 gpt/disk-26 gpt/disk-27 gpt/disk-28 gpt/disk-29 gpt/disk-30 gpt/disk-31 gpt/disk-32 gpt/disk-33 gpt/disk-34 gpt/disk-35 root@pt-storage2:~ # zfs list NAME USED AVAIL REFER MOUNTPOINT data 695K 241T 201K /data root@pt-storage2:~ # zpool create data raidz2 gpt/disk-00 gpt/disk-01 gpt/disk-02 gpt/disk-03 gpt/disk-04 gpt/disk-05 gpt/disk-06 gpt/disk-07 gpt/disk-08 raidz2 gpt/disk-09 gpt/disk-10 gpt/disk-11 gpt/disk-12 gpt/disk-13 gpt/disk-14 gpt/disk-15 gpt/disk-16 gpt/disk-17 raidz2 gpt/disk-18 gpt/disk-19 gpt/disk-20 gpt/disk-21 gpt/disk-22 gpt/disk-23 gpt/disk-24 gpt/disk-25 gpt/disk-26 raidz2 gpt/disk-27 gpt/disk-28 gpt/disk-29 gpt/disk-30 gpt/disk-31 gpt/disk-32 gpt/disk-33 gpt/disk-34 gpt/disk-35 root@pt-storage2:~ # zfs list NAME USED AVAIL REFER MOUNTPOINT data 695K 241T 201K /data --- These are 10TB drives, so the numbers for the 3 vdev setup appear to be way too low. Any ideas what is going on there? cu Gerrit
