After running the 3Ware diagnostic script, the status of the array went to OK. A short time later, it reverted to this

Unit UnitType Status %RCmpl %V/I/M Port Stripe Size(GB)

I recently upgraded xorg on my workstation at the office. Immediately I started seeing problems with one of the monitors. It would go empty/blank/black for three seconds, then resume normal operation. Then it would go blank again when I interacted with the screen. In short, that one monitor was completely useless.
Swapping cables […]

I am impressed…. my gmirror array continued to work even after the drives were renamed from da20 and da24 to ada0 and ada1. This happened when I tried out the ahci(4) for my SATA drives.
It’s the type of thing I’m striving for soon in my ZFS array.
All this started when I wanted […]

In a previous post, I wrote about a suspected LIMIT problem. It turns out that suspicion proved correct. The solution was to move to a nested query which limits the underlying data and then allows the outer query to grab all the associated fluff that surrounds it.
Here is the fix to the original […]

The smartmontools package contains two utility programs (smartctl and smartd) to control and monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (SMART) built into most modern ATA and SCSI harddisks. In many cases, these utilities will provide advanced warning of disk degradation and failure. (The above shamelessly taken from the supplied URL).

I thought I’d run some simple tests, based on a tuning thread I found:
# dd if=/dev/urandom of=./file1 bs=1m count=1024
1024+0 records in
1024+0 records out
1073741824 bytes transferred in 14.283206 secs (75175127 bytes/sec)
And while the above was running:
# zpool iostat 5
