[OpenIndiana-discuss] General ZFS questions

[Michelle Knight]

The mother board is 3Gb/s SATA - http://www.scan.co.uk/products/gigabyte-ga-
h55m-ud2h-intel-h55-1156-pci-e-20-%28x16%29-ddr3-1600-1800-2133-sata-3gb-s-
vga-uatx

Power supply is a Tagan TG480-U01 - 
http://modtown.co.uk/mt/review2.php?id=taganpsu
... so one drive is on a molex connector. I'll keep an eye on the correlation 
and possibly replace the PSU.


So the system currently comprises of the following...

Internal SATA 1 - 40gig SSD system drive
Internal SATA 2 - 40gig SSD system drive
Internal SATA 3 - 2tb Seagage
Internal SATA 4 - 1.5tb Samsung
Internal SATA 5 - 1.5tb WD

External SATA (same "channel" as the internal) - 2tb WD
USB external - 2tb WD

The external drive bay is using its own power supply.

Everything is guarded by UPS with smoothing.


The box is running OI 148 and was left overnight doing a replace on the 
external ZFS set.

This was done because the PCI card I installed to give extra E-sata ports 
wasn't working as it should; very slow due to some compatability mode. Slower 
than USB even. http://www.amazon.co.uk/gp/product/B001O9KEKM/ref=oss_product - 
the jumper seems to knock out the on board BIOS, which has to be done or it 
won't work with Apple (according to the instructions) and also OI (by 
experiment)

Anyway, it was left doing a resilver last night, after I moved one drive from 
the card to the USB channel (the machine was powered off when the switch 
occurred, I would have expected that on reboot, the machine would have seen 
the set and mounted it, but apparently it still thought the drive was still on 
the PCI expansion card and then marked the set as degraded, leaving me with no 
real option but to do a zpool replace. I didn't want to risk an export/import) 

...and I woke up this morning to no drive activity. When I asked for a zpool 
status, the machine hung.  

On restarting the machine, the resilver picked up where it had left off, at 
about 300gig on the 1.25tb external mirror.

These are the last few messages ... presumably before the replace hung...
