[ProgSoc] James' impending data tragedy



 Well .. it's certainly looking that way to me.

 Can someone(s) else please offer some input here?  I'm about to be
 at the wrong end of a dial-up link for a week, and LVM isn't my
 forte, and, well, it has to be said .. RH blows the big one, but I'm
 trying to kick the 'You installed WHAT?!' habit.

 The following information is offered for your collective erudition.

 I think what needs commenting on most is just how borked this
 installation is, whether it's gone haywire since the LVM stuff was
 set up, or if the LVM stuff is one of the symptoms of the system
 doing the bork (to use the vernacular).  The hard errors (see the
 tail end of the dmesg stuff below) make it clear there are some
 serious hardware issues with the drive in question .. and yes,
 James has been instructed to ddrescue the contents of /dev/hdc

 Ideas on recovering data from said dd.image would probably also
 be well received by our newest member in need.

 Does FC really go and set up LVM's like this while you're not
 looking?  It seems a gratuitously ugly way of setting up a system
 (yes, I know that if you do the 'I'm an idiot' installation of Debian,
 you end up with a pretty fugly partition table too ... but really,
 this is just taking the piss, isn't it?).


 dmesg (slightly abridged) follows ... highlights for me include:

 ] Kernel command line: ro root=/dev/VolGroup00/LogVol00

 ] hdc: dma_intr: status=0x51 { DriveReady SeekComplete Error }
 ] hdc: dma_intr: error=0x40 { UncorrectableError }, LBAsect=337, sector=328
 ] ide: failed opcode was: unknown
 ] end_request: I/O error, dev hdc, sector 328 
 ] Buffer I/O error on device hdc, logical block 41

 and :

 ] EXT3-fs error (device hdc2): ext3_check_descriptors: Block bitmap for group 0 not in group (block 1853189987)!
 ] EXT3-fs: group descriptors corrupted
