These things don't "just happen" automatically.

As you are probably aware, OES2 SP3 is very old. You definitely should upgrade to a current version.

Before we can help you prevent this we need to determine what might be causing it and you have provided no information at all.

  • What else can you tell us about your system?
  • What applications are running on it that access the NSS volumes?
  • Is there only one NSS volume involved?
  • Does it happen to only some files and folders or to all of them?
  • When did this start happening?
  • Did you make any changes to this server just prior to this happening?
  • Are there any new users who may be causing this to happen? 
  • Did you check /var/log/messages around the time this started happening for any clues?

Hi,

Thanks for your reply!

  • What else can you tell us about your system? Our tree is with mixed platforms running Novell 6.5 SP7 & OES 2 Linux servers. We have observed this problem on the server running OES 2 Sp3 & SUSE Linux ENT Server SP4. Please suggest if anything could be done with UTF settings to prevent this problem. 
  • What applications are running on it that access the NSS volumes? This is just a file server attached with HP 3PAR Storage.
  • Is there only one NSS volume involved? So far, we have found this problem on only one volume. We need to investigate for the remaining volumes.  
  • Does it happen to only some files and folders or to all of them? Only few files / folder names are getting effected.
  • When did this start happening? We have observed recently only but not sue when it was started.
  • Did you make any changes to this server just prior to this happening? No
  • Are there any new users who may be causing this to happen? No
  • Did you check /var/log/messages around the time this started happening for any clues? No idea exactly when it was started. Attached the log for for your reference.

@ahleia 

I scanned the file you attached. 

  • Start date: 2019-10-13
  • End date:  2020-03-18
  • Number of lines: 19,193

This is one of the things I noticed: This sequence appears more than 200 times and usually at 18:28 hrs, 19:28 hrs, and 23:28 hrs:

NW21OES kernel: Snapping Device(Maj, Min): (8, 3),BlockSize: 4096, NumSectors: 47186921, RelocFileName: //.symantec/sda3, NumOfRelocEntries: 175806.EnableVtrack: 0, doNotTouchVtrack: 1, App PID: 8391.
NW21OES kernel: kjournald starting. Commit interval 5 seconds
NW21OES kernel: EXT3-fs: snap8_3: orphan cleanup on readonly fs
NW21OES kernel: ext3_orphan_cleanup: deleting unreferenced inode 5046310
NW21OES kernel: ext3_orphan_cleanup: deleting unreferenced inode 14959910
NW21OES kernel: EXT3-fs: snap8_3: 2 orphan inodes deleted
NW21OES kernel: EXT3-fs: recovery complete.
NW21OES kernel: EXT3-fs: mounted filesystem with ordered data mode.
NW21OES kernel: Moved the state to DEVICE_UNSNAPPED.
NW21OES kernel: Deleted COW and released the SnapAccessDevice.

The first thing I would do is to run an NSS poolverify to check for any general filesystem errors. If there are specific files and folders being affected, check the dates on these to see when they were last modified. That may provide some additional clues.

If anyone else has additional suggestions, please chime in!

Hi,

There was no file system errors found after NSS poolverify. Please suggest if anything could be done with UTF or any other settings to prevent this problem. 

Thank You!

Before we can think about preventing it we have to determine what is causing it! More information is needed!

Check the date and time on the affected files. Is there a pattern? Were they changed on the same date or around the same time?

Is their a user or group of users who had access to all of them?

The filename could have been changed or the old file deleted and a new one created (using only lower case).. If you have salvage enabled in your NSS volumes, go to the folder(s) where the files reside, right-click, then choose salvage. You will see a list of previously deleted files. You may see the userid that was logged on when the file was deleted. You may also see several deleted copies of the file some of which may show names with different case letters. That might help determine when the change occurred. 

Does this happen only to certain types of files, for example, .doc or .xls?

Previously you mentioned that this issue only occurred on one NSS volume. What makes this volume different from your other volumes?
