Is someone used to Winslow likely to be confused in Sun City?

(I've never been to either (or, within my memory, the US at all))

Yes, I know.

I'm not complaining; just pointing it out in case someone wants to 
respond to the mis-attributed text.


I think Gene Heskett is right -- somebody (and/or their mailer) boogered 
the indentation levels along the way once the levels got too deep.  (I 
have to pay careful attention not to do exactly that when I'm editing 
down previous content in a reply.)

The reason Redhat dropped btrfs support is because it currently has no
native cryptographic function. And from the various threads I've read on
the topic there is no easy answer to the problem.

Red Hat's former filesystem maintainer Josef Bacik said it was
simply because Red Hat now lacks engineers familiar with btrfs.

How could it see its UUID on multiple disks with the default md 
superblock format 1.2 ?

Is btrfs mature enough to use in enterprise applications?

If you are using it, I’d like to hear from you about your experiences —
good or bad.

My proposed application is for a small community radio station music
library.
We currently have about 5TB of data in a RAID10 using four 3TB drives, with
ext4 over the RAID.  So we’re about 75% full, growing at the rate of about
1TB/year, so we’ll run out of space by the end of 2018.

I’m proposing to go to three 6TB drives in a btrfs/RAID5 configuration.
This would give us 12TB of usable data space and hold off til the end of
2024 before needing the next upgrade.

Will it work?  Would I be safer with ext4 over RAID5?

Thanks in advance!
Rick


For production I would stick with RAID10 over RAID5 and XFS over ext4 since
its made for large files which suits your media storage user case. It also
provides for file system backups and restore via xfsdump/xfsrestore and I
also find xfs_freeze useful for consitent backup in case of secondary db
backup lets say. Basically it has everything that ext4 has and some more.

As others have mentioned you should consider ZFS too its been stable for
the past year on linux and the features like compression, dedup, snapshots,
various types of storage pools and even builtin NFS are hard to overlook.
