ZFS benchmarking ideas

Tuesday, April 5th, 2011

I’m about to double the RAM in my ZFS system. It will go from 4GB to 8GB.
Right now, I have:

real memory = 4294967296 (4096 MB)
avail memory = 4100382720 (3910 MB)

I’m not interested in any big extensive benchmarks. I just want something simple. Hence:

$ cd /storage/bonnie/
[dan@kraken:/storage/bonnie] $ ls -l
total 0
[dan@kraken:/storage/bonnie] $ […]

More RAID oddness

Thursday, August 26th, 2010

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

$ sudo /usr/local/sbin/tw_cli info c0 u0

ZFS - some initial testing

Friday, March 5th, 2010

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

mirroring the hard drive

Friday, March 5th, 2010

Tonight’s goals:

Install a second HDD
get gmirror running
install the remaining 5×2TB HDD
add the two RAID cards

After adding in the second HDD for the OS, dmesg shows this:

ad4: 76319MB <seagate ST380815AS 4.AAB> at ata2-master UDMA100 SATA 3Gb/s
acd0: DVDR <tsstcorp CDDVDW SH-S223C/SB01> at ata3-master UDMA100 SATA 1.5Gb/s
ad8: 152587MB <wdc WD1600AAJS-75M0A0 02.03E02> at ata4-master UDMA100 SATA 3Gb/s

The following shows […]

Photos of initial assembly

Wednesday, March 3rd, 2010

Tonight I put together some of the system. The motherboard, CPU, RAM, and PSU have been installed. The system POSTs, but nothing else. Next step: add a couple of HDD and then install FreeBSD 8.

Wrong Ram Again!

Sunday, February 28th, 2010

It seems I cannot use registered ECC RAM in ASUS M4A79T Deluxe m/b.
So I’m going with Patriot Signature 4GB (2 x 2GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 (PC3 10600) for $130 instead.

Server progress

Sunday, February 28th, 2010

The parts I ordered last week arrived on Friday. Unfortunately I forgot to order the RAM. It turns out the RAM I had selected was the wrong RAM; it was DDR2. The m/b takes DDR3. But I didn’t find that out until after I ordered it on Saturday, along with two […]
