703348 - Increase CCACHE max cache size

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P3)

Description

[John Hopkins (:jhopkins)]

Adding Thunderbird builds to the build pool will demand a larger maximum CCACHE cache size so we don't negatively impact cache hits.  Currently set to 5GB max; we may want to double that to 10GB.

Comment 1

[John Hopkins (:jhopkins)]

catlee mentioned the Linux VMs have small drives and will need to be redone to support a larger cache size.

Great idea for the ix boxes. There are some linux64 VMs with the same issue as the Linux32 VMs, and would be worth checking how the 80G disks the moz2-darwin* get used too.

Comment 3

[Chris Cooper [:coop] (he/him)]

Assigning to John since this will be a prerequisite for getting Thunderbird build from the same pool.

Comment 4

[John Hopkins (:jhopkins)]

Returning to the pool so others can help with this.

It's been 1 hour and I haven't seen any uptake on this change yet.  The hosts I looked at are: linux-ix-slave02 and try-linux-slave04

Comment 9

[John Hopkins (:jhopkins)]

I spot-checked the two hosts in comment#8 and they both now have a max ccache size of 10GB.
