From bothunbr at yahoo.com Mon May 3 15:25:41 2010 From: bothunbr at yahoo.com (Brad Bothun) Date: Mon, 03 May 2010 19:25:41 -0000 Subject: [Lugstuff] Introduction.. Message-ID: <65497.14816.qm@web54106.mail.re2.yahoo.com> Hello all, I just thought I would take the opportunity to introduce myself before the meeting tonight. I'm Brad Bothun, I just moved here from Chicago at the end of January. I've been supporting Linux since 97-98 when I was introduced to Suse (I think it was ver5) when I ran out of IPs on a network and used Linux and ip masquerading because my routers didn?t support NAT/PAT. I?ve been using, supporting, promoting Linux ever since. I joined the list months ago and have been meaning to go the meeting but I keep forgetting to set a reminder. I look forward to meeting everyone tonight.

Hmm, a 2TB max makes it seem like there's A.) still an MBR partition table on there (as it appears you've been told by others) or B.) the kernel was compiled without the "Support for large (2TB+) block devices and files" option. For A, if you have access to Palimpsest (the GUI partitioning tool) then it should be able to tell you (just under the volume name) if it is indeed properly formatted with a GPT partition table. If you want to be sure, you can always select the volume and erase it again with a GPT partition table. As far as command line tools, you already know about parted. If you prefer the fdisk command interface then I'd suggest gdisk (it's what I use an it's quite effective). For B, you can find the option for "Support for large (2TB+) block devices and files" under "Enable the block layer" in menuconfig. If you have a .config (kernel config) sitting around or have access to /proc/config.gz then you can search through either for the option "LBDAF" to see if it was enabled. Considering you said this was RHEL though, I don't see would not be enabled (or included) so I think this is the less likely of the possibilities. As I don't own that particular device or have access to one I'm afraid I can't offer any additional advice. Sorry.

The directions can be found on the website: http://annapolislinux.org/?page_id=23 Hope to see you there. Dave B. mentioned he would like to learn about bug reports and how to file a useful one that developers would accept. If anyone successfully filled a bug report we would like to hear about it. Thanks. >>> Dave's request <<<< I realize that I am probably the only persistent beginner in the LUG.
