7000 Appliance OS (Fishworks)
Symptoms
Symptoms observable by the customer:
- Cannot login to BUI/CLI
- Logging in via SP/console, appliance drops to 'failsafe' shell:
appliance/kit/akd: default:method "exec /usr/lib/ak/akd" failed with exit status 1.
- Failure to configure storage pool - error message is "failed to initialize libzfs".
- Replication failures
Symptoms observable by the Oracle Support engineer:
- aklog may have the following message logged:
akd: failed to start appliance kit: failed to locate metadata schema fma: Too many open files
- Replication failures may log similar messages in rm.ak.txt:
Tue Aug 17 04:21:12 2010: failed to remote insert ak:/replication/action-7fef609f-5e95-c76a-fbf2-a04fd7615f7d: rpc com.sun.ak.stash.teleportFini:
1 failed on remote peer: cannot access object com/sun/ak/replication_action/7fef609f-5e95-c76a-fbf2-a04fd7615f7d: No such file or directory
Tue Aug 17 04:21:12 2010: import of ak:/replication/action-7fef609f-5e95-c76a-fbf2-a04fd7615f7d succeeded in 0.000s
- The /var/ak/logs directory contains very many 'old' log files:
# cd /var/ak/logs
# ls -ltr | wc -l
496 => 496 files
# du -hs .
41M . => total size of logs directory = 41Mb
# ls

< snipped >
Cause
This is a known issue. The root cause of this problem is too many open files by akd.
A few libraries (including libzfs) used by akd have a 256 file descriptor limit.
Known issue - <SunBug 6914407> - akd should globally enable extended FILE stdio (Fixed in 2010.Q1.0.0)
Solution
Recommended action for the customer:
For the fix for this issue, the Appliance Firmware Release should be upgraded to 2010.Q1.0.0 or later.
Oracle Support always recommend that you upgrade to the latest Appliance Firmware Release.
To remove the (excessive) 'old' log files, you will need to engage Oracle Support, by opening a Service Request, so that Oracle Support Services can provide confirmation of this issue and then carry out the appropriate activities to resolve the issue.
Recommended actions for the Oracle Support engineer:
Delete the 'old' log files from /var/ak/logs - see the following wiki document:
