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

[Neulinger, Nathan]

Looks to me like the nbytes value is way out of wack. I get this on the
empty volume:

Mar 12 16:21:34 afs-fs18 volserver[13119]: 1 Volser: CreateVolume:
volume 538199060 (users.nneul.test1) created=20
Mar 12 16:21:34 afs-fs18 volserver[13119]: 1 Volser: WriteFile: Error
reading dump file 1 size=3D2048 nbytes=3D136295336 (2048 of 136295336);
restore aborted=20
Mar 12 16:21:34 afs-fs18 volserver[13119]: 1 Volser: ReadVnodes: IDEC
inode 1=20
