new Nexentastor installation - can't run bonnie

Question

I am new to Nexenta but so far I am liking it. I want to use it to replace Freenas for the ZFS advancements.

Anyways I am noticing sort of bad performance with CIFS (30-50MB/s) so I figured I would run some Bonnie tests.

but bonnie gives me the following error:

nmc@nyx:/Data1$ run benchmark bonnie-benchmark Volume 'Data1' is the only available volume, starting benchmark... Data1: running optimal mode benchmark Data1: generating 4094MB files, using 32768 blocks chown: cannot access Data1/.nmc-bonnie-benchmark: No such file or directory

I do have a pool and then I created a folder inside the pool. I setup Cifs and my one server that I created can access the share and upload files just fine.

Any ideas?

the specs of the server (in case you have ideas on the speed issue without the benchmarks): Core2Duo E6600 2GB of ram (going to go to 6GB as soon) Asus P5Q WS workstation board 6x Seagate 1.5TB SATAII drives, Bios/ICH set to AHCI or whatever it is (getting late!) so no raid is set, just single disks.

I created a single Raidz pool with all 6 disks.

No l2Arc or ZIL (this is just a personal home fileserver)

thanks.

Here is a second benchmark using the command you provided:

Answer 1

Personally, I'd run the bonnie++ benchmark from the command line without the Nexenta wrapper.

First, you'll need to log in as the root user and get into the full command shell mode using:

option expert_mode = 1 followed by !bash

Answer y the prompt that says You are about to enter the Unix ("raw") shell and execute low-level Unix command(s).

From here, you can download and install the proper bonnie++ executable.

# Update the apt package database
root@nyx:/volumes# apt-get update

# Install bonnie++
root@nyx:/volumes# apt-get install bonnie++

# Change to the target directory
root@nyx:/volumes# cd /volumes/Data1/your.cifs.folder

At this point, you can run a bonnie benchmark with or without parameters.
I usually run bonnie++ -u root -n 64:100000:16:64, but you'll be fine running bonnie++ -u root inside of the directory you wish to work in.

Post your results. There are a few tweaks needed for Nexenta when used without SAS or SCSI disks. You should at least see 80-90MB/s sequential write speed to a RAIDZ array. Read speed should be better than that.
