472185 - Create 100gb shared drive in build network

Status: RESOLVED FIXED

(mozilla.org Graveyard :: Server Operations, task)

Description

[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

Can you create a 100gb shared drive, visible in the build network?

We'd like to use this for an experiment. Instead of keeping a copy of each build tree on each slave, we'd like to see if we can keep fewer central copies of each build tree on a shared disk. 

Permissions on this drive should be restricted to usual build network and build IDs.

as this would be used by all slaves, for lots of i/o, this disk should be as fast as reasonably possible.

Comment 2

This will need to be NFS and most likely be off netapp-b where we have a lot of space.  Ideally, netapp-b will also be on Vlan 71.

Comment 3

[matthew zeier [:mrz]]

Aravind, can you do this off the netapp and put it on vlan 71?  Is that possible?

Comment 4

[Aravind Gottipati [:aravind]]

AFAIK, all of our netapp interfaces are on the storage VLAN and we have never set it up to be on any other.  There was a similar situation in the past where build needed a share space for buildlogs and we gave them that space on the thumper.  Is that acceptable for this?

bm-sun-xf01.build.mozilla.org:/export/build_tree in the build network and
qm-sun-xf01.mozilla.org:/export/build_tree on the QA network.

Is there a username and password we should be using to mount with?

1) what username/pswd should we use when connecting to this?

2) pls confirm who (outside of build group) has access to this disk?

Comment 8

[matthew zeier [:mrz]]

nfs doesn't require username/passwords. Shares work fine any Vlan71 build hosts:

[root@bm-admin01 ~]# mount bm-sun-xf01.build.mozilla.org:/export/build_tree /mnt
[root@bm-admin01 ~]# df -t nfs
Filesystem           1K-blocks      Used Available Use% Mounted on
bm-sun-xf01.build.mozilla.org:/export/build_tree
                     104857600   4911104  99946496   5% /mnt

Cool, thanks mrz. Using bm-sun-xf01.build.mozilla.org did not work, but thanks to catlee's suggestion, I tried using 10.2.71.136 instead and that worked.



Leaving this open while we confirm who has access to this drive.

Here are the acls on those shares.

rw allowed from anyone on 10.2.71/24 and 10.2.73/24

root writes allowed from anyone on 10.2.71/24 and 10.2.73/24

No other network is allowed to access those shares.

Comment 11

[Nick Thomas [:nthomas] (UTC+12)]

Could you add 10.2.90/24 too ? Build machines spilled into another vlan through sheer weight of numbers.

Comment 12

[Aravind Gottipati [:aravind]]

Done, it should be accessible from the 10.2.90/24 subnet as well.

Comment 13

[matthew zeier [:mrz]]

Netmask is a /23 - can you update?

Comment 14

[Aravind Gottipati [:aravind]]

Done.
