PowerEdge 2900 iSCSI Performance Problems w/ FreeBSD

Friday, June 19th, 2009

Got a new storage server, it’s a PE2900 from Dell. Installed FreeBSD 7.2 on it, rebuilt the kernel with all the updates and included:
options iscsi_initiator
connected to the iSCSI target across the LAN, then I used:
dd if=/dev/zero of=/mnt/testiscsi/file.out bs=65536
to test the speeds after mounting it. I observed horrific speeds (in the range of 300-500KB/s).

mod_security FTW

The other night, I noticed that popsicle.easymac.org’s mailq was >22,000 message. I figured that was a problem. Turns out one of my users (who’s account I deleted without hesitation) was running a PHP proxy from his ~ directory. Looks like the stupid thing allowed some idiot to download some obnoxious looking perl [...]

Finally, Control-Z gets some work!

The first thing migrated to the new server was popsicle.easymac.org.  It used to be an old P4 machine with no RAM, and some crappy amount of storage, and it’s now something nice!
Everyone who is a user on popsicle should check that everything they had going before is still going!  If not, you know who to [...]

OpenBSD iscsi-target

Wednesday, November 12th, 2008

A while back, I had a random interest to see if FreeBSD could be used as an iSCSI target.  Since FreeNAS could do it, I figured the ability would be built into FreeBSD, but I was wrong.  After a bit of Googling, I found that somebody ported the OpenBSD version of iscsi-target over to FreeBSD.
I [...]

named inside a FreeBSD jail

Monday, September 29th, 2008

If you’ve ever tried to run named inside a FreeBSD jail you’ve seen this error:

/etc/rc.d/named: WARNING: devfs_domount(): Unable to mount devfs on /var/named/dev
devfs rule: ioctl DEVFSIO_RAPPLY: Operation not permitted
devfs rule: ioctl DEVFSIO_RAPPLY: Operation not permitted

The reason for this is that by default in FreeBSD named tries to run within a chroot. The chroot for [...]

I’m not creative enough for this, and you can’t help me.
