Issue with Glance

Hi - we are getting the following error(s) when trying to run Glance on HP11.31:

MI: Sun Aug 16 20:05:50 2020

== End of Error Msg =============================
 
However we believe the "not enough space" is a false alert and its an issue with shared memory (shmmax).
 
dmesg shows me this:

 dmesg | grep -i phy

    physical page size = 4096 bytes, logical page size = 4096 bytes

    Physical: 134106344 Kbytes, lockable: 102362192 Kbytes, available: 116367472

 Kbytes

And the current value for shmmax is 4398046511104

 

Can you let me know if this needs to be increased and how this is done and whether a reboot of the server is required.

Many thanks in advance.

Re: Issue with Glance

The error message is a bit misleading. It sounds like your mountpoints are out of space.
But in reality, MIDAEMON has run out of memory to hold information about the listed mountpoints.

You can tell MIDAEMON to start with more space the rc script ovpa in /etc/rc.config.d.
Modify the line:

export MIPARMS=
 Add this option: -smdvss <value>
as in:
export MIPARMS="-smdvss 200M"

200M is just a suggestion. This system appears to be a large one with lots of lvols.

Re: Issue with Glance

Sorry - still getting same error.

ovpa looks like this:

MWA_START=1
MWA_START_COMMAND="/opt/perf/bin/mwa start"
MWA_PROTOCOL=http
export MIPARMS="-smdvss 200M"

Should I increase the 200M?

Re: Issue with Glance

Usually MIDAEMON will automatically request what it needs. You can try 400M, even 800M.
But check your kernel parameter for the maximum size for a shared memory segment: kctune shmmax

Note: smdvss is a limit for MIDAEMON.
What version of Glance and HP-UX are you running?

Re: Issue with Glance

Thanks Bill - I have updated the value to 800M:

export MIPARMS="-smdvss 800M"

All seems to be working.
