Successes and failures at inf.ed.ac.uk

## VirtualBox failure, HP 7100 success

• I have my f12 VirtualBox client installing to the point where the fstab component attempts to make filesystems. The installation fails at that point every time I try it, telling me that the disk doesn’t appear to exist. When I try the same mke2fs command that the fstab component just got a failure from, it succeeds for me perfectly. Alastair saw the same thing several weeks ago but with him it was only an intermittent problem, whereas with me it’s happening every time. Alastair suggested setting fstab.dopartition_sda to false then trying again. This does get the install past the mke2fs stage and on to updaterpms.
• Next problem with the install: updaterpms installs a few dozen RPMs then fails with multiple disk errors. This happens repeatably: I’ve now tried three installs in a row and all fail after installing a few dozen RPMs. Alastair suggested changing the virtual machine disk from IDE to SATA. No joy. The install fails at the same point each time: during the installation of the glibc-common RPM.
• I tried turning off the vm’s use of hardware virtualisation features. This makes it slower, and the installation procedure actually manages to install the glibc-common RPM this way, but it still fails a few packages later on: “Buffer I/O error on device sda1″, etc.
• There’s a sense of relief in the MPU today: Stephen has tried the Dell Optiplex 780, the stop-gap new PC choice that’s been forced on us, with our standard SL5 installation and has found no apparent problems. Phew.
• I’ve been given an old HP 7100 to test f12 on. Apparently they’re proving to be more durable than our (newer) Dell GX620s which are dropping like flies, so the plan is for our 7100s to have a productive old age. Anyway, it tests out OK; F12 works fine; the beast even suspends and resumes successfully. It now has an entry in the test results table.
