Symptoms

Example node firmware assessment failure: 
Isilon-1# isi_upgrade_logs --get-fw-report
Warn : Failed to Create Directory [/ifs/data/Isilon_Support/upgrade_errors_logs] with error number[30] "Read-only file system" : File Name : /b/mnt/src/isilon/lib/isi_upgrade/Util.cpp : Line Number : 379
Unable to open or extract the file UpgradeLog-1.db from archive: UpgradeArchive-2021-12-23T11:49:19.381Z-2021-12-23T11:51:15.854Z

Example of OneFS assessment failure: 
Isilon-1# isi_upgrade_logs -a
Assessment Errors found, Attempting to find and extract logs from archive
Warn : Failed to Create Directory [/ifs/data/Isilon_Support/upgrade_errors_logs] with error number[30] "Read-only file system" : File Name : /b/mnt/src/isilon/lib/isi_upgrade/Util.cpp : Line Number : 420
Unable to open or extract the file UpgradeLog-5.db from archive

Cause

The isi_upgrade_logs command attempts to extract details to /ifs/data/Isilon_Support/upgrade_errors/logs but fails to do so due to the directory being read-only/writes-disabled as it is a target path for an incoming SyncIQ policy.

Resolution

To be able to use isi_upgrade_logs to review the OneFS upgrade assessment or node firmware assessment results, temporarily allow writes for the SyncIQ policy which has writes-disabled for one of the sub directories to /ifs/data/Isilon_Support/upgrade_errors.
 

WARNING: The command to revert allowing writes should be performed immediately after the assessment results have been gathered. Failure to revert the change causes SyncIQ job failures.


1. Check for incoming SyncIQ policies have writes disabled:

# isi sync target list

From the list of policies, identify which policy has a subdirectory of /ifs/data/Isilon_Support/upgrade_errors as a target path, typically the path found is /ifs/data/.  If there are no SyncIQ policies with one of the subdirectories as its target path, this issue may not apply and further review in to why the directory is read-only should be done.

2. Temporarily enable writes in /ifs/data/ by running the following where <policy-name> is the SyncIQ policy identified in step 1:

# isi sync recovery allow-write <policy-name>

3. Get the assessment details:

  • OneFS upgrade assessment command:
# isi_upgrade_logs -a
  • Node firmware assessment command:
# isi_upgrade_logs --get-fw-report

4. After reviewing the results, revert the allow-write policy change, where <policy-name> is the SyncIQ policy identified in step 1:

# isi sync recovery allow-write <policy-name> --revert
