Gottcha… I thought you meant there was a problem setting a topic/post “Sticky”
Ok, well it’s maintenance day tomorrow and I have to pull one of the core servers that hosts the mail system, the lighttpd server, and a customer VPS, amongst other things … [one of the drives in it’s array failed badly and I use cheap / non hot swap HDD’s]
So, I’ve just [live] migrated all the services off that box onto other cloud nodes leaving it idle / ready for shutdown.
Downtime, around 1s in total … so linux.co.uk and the forums are running in degraded mode atm … notice the slowdown?
I love clouds … :-* … once upon a time I’d either have been paying through the nose for hot-swap kit, or scheduling 2h downtime, or spending a couple of days in advance patching a backup service … all I need now is for hardware manufacturers to stop turning out crappy drives and I’ll be happy … :
Ok, but I hate software raid.
Tips of the day;
- use RAID6 instead of RAID5.
- get / use mdadm 3.1.2 or better
Command line of the day to rebuild a completely screwed RAID 5 array. This is useful if /dev/sda2 has failed, you have replaced it, but one of the other disks then errored while trying to build in the replacement /dev/sda2. Warning: incorrect use of this command and/or incorrect parameters can serious damage your … well … everything.
mdadm --create /dev/md0 -vv --assume-clean --level=5 --chunk=64 --layout left-symmetric --raid-devices=5 missing /dev/sdb2 /dev/sdc2 /dev/sdd2 /dev/sde2
Then of course you need to re-map the failed blocks on the device that errored (badblocks) and following that, re-add the replacement sda2 and watch it rebuild … hopefully … ask me later …
Linux.co.uk is much faster :o
Forums are much quicker aswell… shame about the search bar on the website though
Yes, there’s still a search function if you hit one of the sub pages (News etc) … I will put something back, but that particular plugin was really terribly in terms of performance …
Ok, I’ve added the search bar back on the site … just without the performance hitting “live” feature …
I’ve lost count of how many times you’ve changed the website URL.
Erm, website url has never changed … ???
