[9fans] Fs64 file server, partition boundaries out of range, and `Tvirgo' tag

[9fans] Fs64 file server, partition boundaries out of range, and `Tvirgo' tag

[Gregory Pavelcak]

I've been trying to replace some IDE disks, currently serving as
mirrored worm in my fs64 file server, with some 50G Seagate scsi
drives.  After doing a copydev and changing the config to make use of
the scsi drives, I see two problems.  First, early in the boot
process, I get (I'm not actually sure about the numbers, I have a very
messy hand written note here)

cannot add sd12!plan9 [63,156296385] to disk [0,976937355): partition
boundaries out of range
cannot add sd13!plan9 [63,156296385] to disk [0,976937355): partition
boundaries out of range

These are the 2 drives I'm trying to add.

Then  later, it appears that the server is going to come up, but I get

tag=Tnone/0; expected Tvirgo/6105775 - flushed (6105775)
panic:fworm:checktag 6105775
cpu 0 exiting

I don't know if these two things are related.

Appreciate any help.

Greg

Geoff would be the best one to answer those, but he's
on vacation for another week or so.

Re: [9fans] Fs64 file server, partition boundaries out of range,

It sounds like

	cannot add sd12!plan9 [63,156296385] to disk [0,976937355): partition boundaries out of range

is coming from 9load.  I haven't seen this, but it does sound like
garbled partition tables or a bad disk.  The first block of a file
system contains its configuration block, so if you plan to have an MBR
or other DOS/FAT stuff on the disk, you'll need to skip it.  I do that
on my main file server to allow a small DOS partition.  To do so, use
p(w0)1.99 instead of w0, for example.

`panic: fworm: checktag 6105775' is quite serious.  The fake-worm
bitmap isn't initialised.  Copying fworms is tricky, particularly if
the output device is larger than the input device.  You probably ought
to use copyworm instead of copydev, since copydev just blindly copies
blocks, assuming input and output are the same size, but copyworm
knows how to copy fworms, including reaming the output fworm, thus
creating its bitmap.
