This problem is specific to AIX systems running as translator machines under AFS 3.2a. A fix is currently available. Contact your AFS Product Support Representative if you'll be needing this fix. Kathy Rizzuti AFS Product Support ---------- Forwarded message begins here ---------- From: [EMAIL PROTECTED] Subject: 3.2a, AFS-NFS Translation (afs.ext.trans) To: [EMAIL PROTECTED] Date: Wed, 7 Apr 1993 17:53:15 +22311841 (EDT) For the rs_aix32 system, there appears to be a problem with root.client/usr/vice/etc/dkload/afs.ext.trans in the 3.2a release. (the kernel extension for AFS-NFS translator machines.) The problem is _silent_. The 3.2 afs.ext.trans appears to work correctly with the rest of the 3.2a release. -rwxr-x--- 1 root system 371251 Aug 25 1992 afs.ext.trans -rwxr-xr-x 1 lawrence system 386759 Mar 05 12:31 afs.ext.trans.broken3.2a sum afs.ext.trans* 26445 363 afs.ext.trans 21227 378 afs.ext.trans.broken3.2a The problem we've had is with a Convex C210 at ConvexOS V9.1 as the NFS machine. It shows up with various file writing situations; for instance when moving user files into AFS with "tar" or "cp". Some files get truncated or otherwise munged, without an error message resulting from the writing operation. In one situation, an inital opening & writing operation worked, but subsequent appends to the file failed, again without error. Thus, people were quietly losing data. This is fairly repeatable. I do not know if the problem is specific to Convexen; I rather suspect that it's specific to rs_aix32 translators at 3.2a. But the Convex is the only non-supported machine we run much via translation. I've reported the bug, but I feel the neccesity of sending a note to info-afs since we've had this for a week before we traced it back to the AFS-NFS translation; it can cause lost data (we had users losing mail, which maketh them very restless) and the old binary does fix it easily. What made it tricky is the partial function and lack of (reported) errors. -- -Lawrence Smith, MSC Computing Staff - Cornell Univ., Ithaca, NY [EMAIL PROTECTED] [EMAIL PROTECTED] (607)255-6064 -Cats, Coffee, Chocolate...
