Hi folks,
I just recently build myself a NAS with Oracle Solaris 11 Express.
MOBO: Asus M4N68T-M LE V2 nForce 630a AM3
PCI-e Controller: 2x Exsys EX-3503 with Sil3132 Chipset (latest FW)
HDD: 7x 2000GB Samsung EcoGreen F4 HD204UI 32MB 3.5" (latest FW)
OS: SunOS zaruba 5.11 snv_151a i86pc i386 i86pc Solaris
Since I'm totally new to Solaris I grabed some guides and started playing with creating some zpools. At first there weren't any problems but after some zpool destroy tank the nex zpool create tank ... produced following error message:
Code:
# format

use '-f' to override the following errors:
mirror contains devices of different sizes
That totally blew my mind because it wasn't the case before. A quick iostat -E shows that's indeed true.
Code:

The strange thing though is when I plug the apparently smaller disks from the MOBO controllers to the add-in controllers iostat -E shows 2000398934016 bytes instead of 2000371580928 bytes.
I don't know which is the correct value but like I said before this behavior didn't occur in the beginning. Also what's with the illegal requests
So long story short. My identical devices (they had the exact same Byte count before) are not identical anymore and I'd like to know why that is and how I can fix that. True it's just ~27MB missing so the whole pool would lose some 100MB but I still do wanna know what happened here.
Looking forward to your replies.
Best regards

Hello,
in one default UFS filesystem we have 8K block size (bsize) and 1K fragmentsize (fsize). At this scenary I thought all "FileSytem IO" will be 8K (or greater) but never smaller than the fragment size (1K). If a UFS fragment/blocksize is allwasy several ADJACENTS sectors on disk (in a ... (4 Replies)
