I migrated yet another GroupWise post office from NetWare to SuSE Linux this evening. However, I had undercover help.
The data on the NetWare volume was 65 GB. So we made the ext3 volume 100 GB. Did the initial copy, and had 1% free disk space left. Dang NetWare compressed volumes....
Time to expand the LUN for the new server. The destination box is a Xen VM guest. I'm shady on the details, but after the LUN was altered on the host VM, the entire blade has to be rebooted to see the new space. The admin who was going to take care of it, was going to do it early in this morning, as he normally shows up at 6:00 AM. About midnight, he wakes up: "Oh heck! I'm scheduled to come in late tomorrow!"
Still in bed, he grabs his BlackBerry and establishes a SSH connection to the host VM. Resizes the LUN from the command line and then reboots everything. All is well for me to get the job done tonight (which I did, and it went well).
I did say "undercover" did I not?
