Related Novell TID: "Error Reading File.." on Server with All Dev (04JUL1995)
On some of our test servers, which get quite a workout, we have noticed error messages similar to the following on the NetWare console:
4-20-2001 9:26:56 am: FILESYS-5.10-178 [nmID=60017]
Error reading file NWDIR.JAR.
Offset 000315AEh data stream 0.
Read was requested by user ADMIN on station 6.
File path SYS:JAVA\BEANS\NWDIR.JAR.
This error message means that a user attempted to read data from this file. The disk read returned "Media Error" and the read could not be completed. For some reason NetWare does not Hotfix this data block. We recommend backing up this volume, replacing the disk drive and then doing a volume restore.
The key problem here is that NetWare did not do something with this error. A possible reason is that this is only a temporary error and the read may succeed at some time in the future. However, at this time, NetWare just returns garbage to the user.
For each file that NetWare reports this problem, rename the file to something else. An idea would be to create a root level directory called "badfiles". Rename the file specifying this directory as the destination path. Do not delete the file. Deleting the file will move the file and its data blocks to the deleted file list. Later when you purge the volume, the bad disk block will then be available for another file. The problem will then repeat later on. Now recover the defective file from your backup or other sources.
