Dear users,
Following on from our recent system upgrades we have experienced some instability on one of our file servers that provides group and scratch group spaces.
We believe we have tracked this down to a rapid growth in storage by a number of groups resulting in disk space running low. To remedy this we started emergency maintenance to upgrade the filesystem technology of these group spaces last night that will then allow us to increase the amount of capacity available. Unfortunately this process is still running this morning and is likely to continue throughout the morning. As a result there is currently no access to scratch group spaces. Group spaces are available.
To speed up the upgrade of these file systems the cluster is currently disabled, queued jobs will run once the upgrades complete.
To minimise the chance of this problem repeating itself in the future we will also be upgrading all the remaining (non-group) filesystems this evening (Thursday 1 Oct) between 7pm and 9am the following morning. All YNiC systems will be unavailable during this time.
We apologise for the inconvenience this will cause and for the stability issues over the past few days.
Best wishes, Paul.
