[zfs-discuss] mixing WD20EFRX and WD2002FYPS in one pool
Hi, after a flaky 8-drive Linux RAID10 just shredded about 2 TByte worth of my data at home (conveniently just before I could make a backup) I've decided to both go full redundancy as well as all zfs at home. A couple questions: is there a way to make WD20EFRX (2 TByte, 4k sectors) and WD200FYPS (4k internally, reported as 512 Bytes?) work well together on a current OpenIndiana? Which parameters need I give the zfs pool in regards to alignment? Or should I just give up, and go 4x WD20EFRX? Secondly, has anyone managed to run OpenIndiana on an AMD E-350 (MSI E350DM-E33)? If it doesn't work, my only options would be all-in-one with ESXi, FreeNAS, or zfs on Linux. Thanks, -- Eugen ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I think it's the ASUS E35M-I [1]. I use it as a NAS, so I only know that the SATA ports, USB port and network ports work - sound, video acceleration, etc., are untested.

Thanks, this is great to know. The box will be headless, and run in text-only mode. I have an Intel NIC in there, and don't intend to use the Realtek port for anything serious. I intend to boot off USB flash stick, and runn OI with napp-it. 8 GByte RAM, unfortunately not ECC, but it will do for a secondary SOHO NAS, as data is largely read-only.

I have an Intel NIC in there, and don't intend to use the Realtek port for anything serious. My laptop based on AMD E2 VISION integrated CPU and Realtek Gigabit had intermittent problems with rge driver (intr count went to about 100k/sec and X11 locked up until I disconnected the LAN), but these diminished or disappeared after I switched to gani driver (source available from internet). OI lacks support for the Radeon chips in my CPU (works as vesavga). And USB3. I intend to boot off USB flash stick, and runn OI with napp-it. 8 GByte RAM, unfortunately not ECC, but it will do for a secondary SOHO NAS, as data is largely read-only. Theoretically, if memory has a hiccup while scrub verifies your disks, it can cause phantom checksum mismatches to be detected. I am not sure about timing of reads and other events involved in further reconstitution of the data - whether the recovery attempt will use the re-read (and possibly correct) sector data or if it will continue based on invalid buffer contents. I guess ZFS being on the safe side should double-check the found discrepancies and those sectors it's going to use to recover a block, at least of the kernel knows it is on non-ECC RAM (if it does), but I don't know if it really does that. (Worthy RFE if not). HTH, //Jim Klimov ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

There is a way, but you don't give the parameters to zfs, see http://wiki.illumos.org/display/illumos/ZFS+and+Advanced+Format+disksOverriding the Physical Sector Size.

Actually, you may not even need to do that, if the vdev specification contains some disks that report 512 sectors and some that report 4k sectors, it will use 4k sector alignment on all devices in that vdev. So, as long as each vdev you make has at least one EFRX in it, you will get ashift=12, which is what you want.
