[gentoo-user] Anyone used NILFS2?

[Paul Hartman]

I'm very interested in NILFS2 and considering using it as rootfs. I
read some good reviews and seems to perform okay in benchmarks. The
automatic checkpoints/snapshots sounds like it could be useful. (I'm
thinking especially to see prior versions of files in /etc for
example.)

Have any of you used NILFS2 and have any failures or success to report?

I had some issues with NILFS2. It sometimes "breaks" and still has no
checking-repairing utility. I never lost my data, but garbage collector
couldn't work.

Such things happen rarely, but may be dangerous in production.

If you're looking for a flexible filesystem, try btrfs. It is quite nice.
It still needs some help in the performance department, but given a recent
Linux kernel (say, 3.2) it works wonderfully. I use its snapshots and COW
functionality the most.

The only downside to it is that it sometimes is slowish when I do many
writes in a short period of time. Also, fsync() still takes awhile, so
applications that use it liberally, such as dpkg, can run very slow.
Things which use SQLite also suffer under heavy write loads.

For that reason alone, I wouldn't yet use it on a database server. I would
use it on a read-mostly file server, however.
