If you do use XFS, make sure you have enough space in RAM+swap to accomodate the xfs_check tool, which is notoriously memory-hungry. My suggested filesystem layout is something like: 30GB /, using ext4 10GB swap remainder of space in a separate partition mounted on /var/lib/backuppc. I've found I needed a good 5GB or more swapfile to accomodate fscking a 9TB filesystem; but that's only the rougest metric. So I'll suggest 10GB of swap. It seems like a horrible waste of space since most will never be used; but compared to a multi-TB filesystem its vanishingly small, and it simplifies the process when you fsck your XFS filesystem (which shouldn't be necessary; but hardware does fail, and when you have hardware errors, sometimes you need to fsck). -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com |
