Other Days

January 30th, 2013

nfs1 ready to come back online

I discovered that I did run a cable between the NFS's… tried bringing NFS1 back up, but it caused load to be extraordinarily high and impacted performance, so I took it back down. Will likely aim for a weekend resync.

January 23rd, 2013

day of LAIR

Spent pretty much the whole day in the LAIR— 9am-6pm. It was a blast. The multiseat machines held up admirably.

January 22nd, 2013

stuff

My classes pretty much all start tomorrow.. taking advantage of this free Tuesday to put finishing touches on things. Claimed one of the pod spots by LAIReast as my unofficial office.

January 19th, 2013

VLAN overhaul

Spent some quality time on this Saturday applying some sanity to the network. Made some pretty diagrams.

January 18th, 2013

Startup

The semester starts next week! We'll be ready. Deployed the interim replacement c107a-fs.

January 17th, 2013

more re-assembly

Yet more arranging, organizing.

January 16th, 2013

more reassembly

Continue to assert some order to the new room.

May have gotten LAIReast back up/juicebox talking to the outside world…

January 15th, 2013

campus connection arrives

Lab46 is once again accessible from the world… new IP: 143.66.50.9

Further refinements made. Some attempt at getting LAIReast back up- figuring out VLANs, running cables, etc.

January 14th, 2013

LAIR move, day 2

The second of two big hauls took place, and we began our first re-assembly of the LAIR.

Got LAIRwest back up and running, no campus connection as of yet- scheduled for tomorrow.

The new pod layouts have commenced. Tri-Force design.

January 12th, 2013

Fedora Multiseat, take two

Attempting a second Fedora install on the second of 3 or 4 flake pods… both to verify my ability to reproduce similar results, but also to start contemplating documentation. Both drives so far have been 160GB SATAs, which seems a waste of resources… once the dust settles, I may well want to swap them out with smaller drives (or figure out how to boot from network and into RAM).

time sync issues (still)

Looks like that didn't fix it… they persist.

time sync issues (Again)

Turns out the issue still persisted… added more options… the following stanza, as a whole, was added today to address the problem (in /etc/dovecot/dovecot.conf):

mmap_disable = yes
dotlock_use_excl = no
mail_nfs_storage = yes
mail_nfs_index = yes
lock_method=dotlock

time sync issues with dovecot resolved

I thing I may have finally solved the dovecot time sync issues… not sure why they were only present now, with only 1 NFS server present, but hey…

According to:

The option lock_method=dotlock might work well.. and sure enough, it did. There are some other NFS options, but they are not currently applied (as far as I can tell).

January 11th, 2013

moving commences

B&G arrived to start moving stuff… I spent the morning (and pretty much the day) wrangling equipment into piles to be taken to Goff Road.

time sync

Trying to address the persistent claimed time sync issues with dovecot… all involved machines have been manually rsync'ed against caprisun.. clocks do not appear to be a problem. Issue persists.

January 10th, 2013

instaLAIR location

It has been decided we are to move the LAIR to Goff Road for the semester, room J106.

I ventured over there and took a look… a little smaller, but could conceivably work in the short (semester) term.

B&G will be assisting in our move… preparing necessary equipment for transport.

January 9th, 2013

Minimal services restored

With mounting student and user demands for Lab46 availability to resume, I finangled some things to get the LAIRwest rack back up and running.

As anticipated, there were no problems standing in my way.

Logs are generally noisier due to various co-services in LAIReast and LAIRsouth being unavailable, and there's some interesting time sync error going on with dovecot on mail.
