Hi. I am new to Isilon and got to plan a OneFS upgrade on 2 clusters. Ive been reading the upgrade documentation and one of the issues we have is that /ifs is at 92% on these 2 clusters.
I am looking at ways to reduce this below the 90% max threshold as per the upgrade documentation and easiest option is to start with some housekeeping and finding stuff that is not being accessed and getting rid of it if possible. I thought it would be easy but not proving so. I have logged into OneFs and also found we are using InsightIQ but i am struggling to find a report that will simply list the filesystems and last access/modification dates. And i cant find anything via cli that will help me.
Does anyone have any ideas on how i can simply produce a report of all the filesystems and have their last accessed and modified timestamp please?
Isilon doesn't have filesystems per se, it has one filesystem. That filesystem is called OneFS, which yes, is also the name of the operating system, and that can be confusing. So you have one big/really-big filesystem with lots of files and folders. The easiest place to look for space is to see if you have any extra/old snapshots laying around. `isi snap ls`. You would want to delete the oldest snapshots first, since deleting newer ones is may not necessarily free up lots of space. Also just because you delete a snap doesn't mean that the space is immediately available back to the filesystem. There is a built-in job that comes through and cleans them up called 'SnapshotDelete', which you can run manually, or will run automatically on a pre-defined interval. If you want to look for old data, just navigate the tree using ls -l, or using InsightIQ, to look for file ages.
Okay thanks. We have removed old snaps and have snapshot delete running so will give InsightIQ a go and try work out where to get the info from. thanks
