[ale] Centos

[Jim Kinney]

XFS has been out of beta for 10 years. It's been an install option since
RHEL5.

XFS IS the default filesystem in RHEL7. So going with a default is the
better choice here.

XFS tools:
/sbin/fsck.xfs
/sbin/mkfs.xfs
/sbin/xfs_repair
/usr/sbin/xfs_admin
/usr/sbin/xfs_bmap
/usr/sbin/xfs_check
/usr/sbin/xfs_copy
/usr/sbin/xfs_db
/usr/sbin/xfs_estimate
/usr/sbin/xfs_freeze
/usr/sbin/xfs_fsr
/usr/sbin/xfs_growfs
/usr/sbin/xfs_info
/usr/sbin/xfs_io
/usr/sbin/xfs_logprint
/usr/sbin/xfs_mdrestore
/usr/sbin/xfs_metadump
/usr/sbin/xfs_mkfile
/usr/sbin/xfs_ncheck
/usr/sbin/xfs_quota
/usr/sbin/xfs_rtcp


EXT tools:
/sbin/badblocks
/sbin/debugfs
/sbin/dumpe2fs
/sbin/e2fsck
/sbin/e2image
/sbin/e2label
/sbin/e2undo
/sbin/fsck.ext2
/sbin/fsck.ext3
/sbin/fsck.ext4
/sbin/fsck.ext4dev
/sbin/logsave
/sbin/mke2fs
/sbin/mkfs.ext2
/sbin/mkfs.ext3
/sbin/mkfs.ext4
/sbin/mkfs.ext4dev
/sbin/resize2fs
/sbin/tune2fs
/usr/bin/chattr
/usr/bin/lsattr
/usr/sbin/e2freefrag
/usr/sbin/filefrag
/usr/sbin/mklost+found


They both have an extensive tool chain to do anything needed. They are
different in their operation and require some geektime to move between the
two of them. Over the last 10 years, I've had to get under the hood of both
extX and XFS for problems. Both were recovered. XFS was written at a time
when other filesystems were under-powered and too small for tossing around
multi-terrabyte files found in video production.

It works very well. It's not beta quality by any stretch of the
imagination. It's in production use in many, many locations, some of which
I manage. :-)

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
