Summary:
101318-59 requires a bit of "seasoning" in /etc/system to work
properly on SS1000's.
Most respondents suggested going back to release 54 of the patch, plus
a lot of desperate "me-too's". However, the easiest route for me was
to try the following parameter adjustments in /etc/system, thanks to
sjk@KaPRE.COM (Scott J. Kamin):
We saw the problems you mention when we first installed our systems
6 months ago. We eliminated them by adjucting the values in the
/etc/system file.
Here's what we're running now, 4CPU, 256MB memory:
set ufs_ninode=32768
set ncsize=32768
set nsegkp=1024
set nhbuf=256
set p_nbuf=2048
set bufhwm=16384
set bf:bf_nbufs=2048
set bf:bf_nrmds1=256
set slowscan=0x64
set fastscan=0x2000
set maxpgio=100
I didn't have time to even understand those settings, let alone
tweaking them to a 2CPU/128MB and a 8CPU/192MB configuration, since I
was away for most of the previous 7 days. I just used these same
values and rebooted the machines to have a go and see what happened.
A week later the machines are still up and running (thank God the
latest storms didn't cause long power failures...), no problems have
been observed since then with NFS.
Other managers might go straight to release 64, but I would suggest
having the above mods up your sleeves anyway, preferably knowing what
they do (does the manual cover all those parameters? I don't think
so...).
And hooray to the most unstable Solaris patch! Releases are updated
up to the minute:-):-).
Also mentioned:
- going back to release 54;
- checking whether automount had been stopped before applying the
patch; I saw the msg when doing it, because I installed this patch
through the 2.3.Recommended install_cluster script, which is not wise
enough. On the second installation, I believe I stopped autofs as
recommended but it made no difference. I checked
/usr/lib/autofs/automountd and it is identical to the file in the
patch. Also, the patch log file reports installation OK.
- checking whether 101344-11 (Jumbo NFS patch) was installed; This
patch is part of the 2.3.Recommended cluster and was applied at the
same time.
I apologise for the wrong "From:" field in my msg. This has already
been corrected. See my signature below for the correct address.
