We're looking at getting an HBR (that's a technical term, honkin' big RAID). What I'm considering is, rather than chopping it up into 14TB or 16TB filesystems, of using xfs for really big filesystems. The question that's come up is: what's the state of xfs on CentOS6? I've seen a number of older threads seeing problems with it - has that mostly been resolved?
I have some largish (>20TB) xfs filesystems on CentOS 6, and things seem fine. The one issue I had, quite a while ago (and maybe even in CentOS 5?), was with growing the fs, but I grew one on CentOS 6 recently with no problems.
How does it work if we have some *huge* files, and lots and lots of smaller files?
Define "huge". It seems fine for our use with multi-dozen-GB files (possibly getting to >100GB files) and many small files, but our load is generally not that heavy.
At the moment, files that are tens of gigs, but I would not be at *all* surprised to see another decimal point there in the next year or two. HBR - a Jetstor 742 with 42 4TB drives.... I'm assuming they'll want me to do RAID 6 for this, as we've been doing on other RAIDs.
