Today our production Citrix NetScaler broke. The box wouldn’t boot and our only backup copy of the config was on the NetScaler itself.
Being the only Unix guy around I attempted to help out the admins working the outage. I SSH’d into the development NetScaler and noticed it runs on FreeBSD.
I suggested fetching the Hard drive and mounting it on a Linux computer. The NetScaler has one SATA (not SAS) disk so my desktop was compatible.
I installed the disk in the Linux tower and mounted the filesystem using the following command:
mount --read-only --type=ufs --test-opts ufstype=44bsd /dev/sda5 /mnt
Once mounted I was able to SCP interesting files to a safe location.
Warning, this procedure might void your warranty. If in doubt, call support first.
