Hello,

We've had some strange file corruption and missing data issues with
Microsoft Excel 2010 on a Windows 7 OpenAFS 1.5.78 client.

1) A user creates an Excel file on their local drive, then copies it to an
AFS RW mount point (via mapped network drive).
2) several clients read the file (no changes made)
3) at some point the file is no longer able to be opened, or it opens but
warns of corruption and missing data

When I recover the file from the backup on the day of the file's
modification timestamp, the restored file is fine. Curiously, the restored
file appears identical to the corrupted file: the file size (bytes) and
timestamp are identical.

The fileservers housing volumes where this has happened are:
 CentOS 6.0 2.6.32-71.29.1.el6.x86_64 with OpenAFS 1.6.0
 RHEL 6.1 2.6.32-131.2.1.el6.x86_64 with OpenAFS 1.4.14

We have upgraded the client to OpenAFS 1.7.2 (we did this just before the
1.7.3 announcement) hoping to fix the issue if it is a bug... Is there any
known issue with 1.5.78 client that could have caused corruption like this?
