[cisco-voip] CM 8.6 to 10.5 common Partition

[Scott Voll]

OK so we had CM 8.6 running on MCS servers with 146 gb mirrored drives.

Now I'm on VM CM 10.5 and the OVA came with a 80 gig drive.

Now I'm bouncing at my 90% used common partition.

is this normal?  is this a bug?  is it that i'm using a 80 gig drive.

Before I open a TAC case... What is the underlining issue?

TIA

Scott

The common partition will float between 90% and 95% capacity by design, and
by default.  You can adjust this if you want to via RTMT Low and High Water
Marks for the Common Partition.

The way the Low and High marks work is like this:  If the system is at 0%
utilzed, then starts to increase to exceed the Low water mark, nothing
happens.  Then when it continues to rise, and exceed the High water mark,
the system will start to purge old log files until the utilization drops
below the Low water mark.  Then the disk will start to fill again, and
repeat this process over and over.  Hence the floating between the 90% and
95%.

When you do an upgrade, it's recommended to move these values from 90/95 to
30/40 to free up space for the upgrade.

High and Low water mark changes for upgrades, see step 4 (note the
descrepency between the normal values here and the above values)
