For Sun StorageTek 5210, 5310, 5220, and 5320 NAS Appliances with NAS OS 4.22, NAS Clients May Experience Intermittent I/O Issues


1. Impact

For Sun StorageTek 5210, 5310, 5220, and 5320 NAS Appliances with NAS OS 4.22(M0), NAS NFS/CIFS clients may experience intermittent I/O errors during certain operations. This may cause applications to unexpectedly fail or exit.

2. Contributing Factors

This issue can occur on the following platforms:
  • Sun StorageTek NAS Appliances 5210, 5220, 5310, 5320 without NAS OS 4.22(M1) as delivered in patch 119352-11

Notes:
  1. Prior releases are not affected. This issue was introduced with NAS OS firmware 4.22 M0, and may affect systems running that version.
  2. The issue may occur more frequently during bulk creation of files or directories, especially on fragmented volumes.

To determine if a system is affected, issue the "version" cli command. The output will be similar to one of the following:

NAS> version
StorageTek  Model 5210 NAS  S/N SE52102005102101 Version 4.22 M0 (Build 160)
StorageTek  Model 5310 NAS  S/N SE53102005102101 Version 4.22 M0 (Build 160)
StorageTek Model 5310C NAS S/N SE5310C2005102101-H1 Version 4.22 M0 (Build 160)
StorageTek  Model 5220 NAS  S/N SE52202005102101 Version 4.22 M0 (Build 160)
StorageTek  Model 5320 NAS  S/N SE53202005102101 Version 4.22 M0 (Build 160)
StorageTek Model 5320C NAS S/N SE5310C2005102101-H1 Version 4.22 M0 (Build 160)

3. Symptoms

Clients may receive spurious I/O errors (EOI). One or more messages similar to the following may appear in the NAS Appliance system log:

05/05/08 18:09:13 E /d: too many xa_n_op, shrink failed, n_op 
20061896, n_dirty 28
05/05/08 18:09:13 E /d: too much data in transaction, n_dirty 28

These messages can be viewed using the "logtail" CLI or via the NAS OS Web Admin:

View System Events ->  Display System Log

4. Workaround

There is no workaround for this issue. Please see the Resolution section below.

5. Resolution

This issue is addressed in the following release:
  • NAS OS 4.22(M1) as delivered in patch 119352-11 (for Sun StorageTek 5210, 5220, 5310, 5320 NAS Appliances)
