[OpenAFS-devel] error report with hardly any useful information, an assert in file server code

[Neulinger, Nathan]

I have a reproducible error condition with the current cvs volserver
code. I can move sw.krb5src between my other file servers (all running
2002-09-18 build) without any problem, but as soon as I try to move the
volume to the file server running current code, it fails:

Mar 12 16:11:19 afs-fs18 volserver[13119]: admin is executing
CreateVolume 'sw.krb5src'=20
Mar 12 16:11:19 afs-fs18 volserver[13119]: 1 Volser: CreateVolume:
volume 536928507 (sw.krb5src) created=20
Mar 12 16:12:12 afs-fs18 volserver[13119]: 1 Volser: WriteFile: Error
reading dump file 1 size=3D2048 nbytes=3D136294776 (-482088960 of
136294775); restore aborted=20
Mar 12 16:12:12 afs-fs18 volserver[13119]: 1 Volser: ReadVnodes: IDEC
inode 1=20

Note - moving volumes OFF of that server works fine.=20

I'm going to try and get some more info, but since this is very
reproducible, I figured it would be a good thing to investigate.

Note - it hapens with ANY volume size, including a freshly created
volume that is completely empty.
