Hi all- What partition type is best/most commonly used for a multi-disk JBOD setup running Cassandra on CentOS 64bit?
The datastax production server guidelines recommend XFS for data partitions, saying, "Because Cassandra can use almost half your disk space for a single file, use XFS when using large disks, particularly if using a 32-bit kernel. XFS file size limits are 16TB max on a 32-bit kernel, and essentially unlimited on 64-bit." However, the same document also notes that "Maximum recommended capacity for Cassandra 1.2 and later is 3 to 5TB per node," which makes me think >16TB file sizes would be irrelevant (especially when not using RAID to create a single large volume). What has been the experience of this group? I also noted that the guidelines don't mention setting noatime and nodiratime flags in the fstab for data volumes, but I wonder if that's a common practice. James
