zfs and xfs are great choices, especially for filesystem snapshots and backup.
personally, i recommend against btrfs due to certain data loss scenarios in RAID 5 setups, which is a common approach for database servers. ----- Original Message ----- From: "max" <[email protected]> To: [email protected] Sent: Thursday, May 24, 2018 12:07:09 PM Subject: Which filesystem are you using? Hi, I'm using CouchDB 1.7.1 on Ubuntu 16.04 with ext4 filesystem and it works great. But I'm gonna migrate my data to a bigger server and I'd like to find some advice about filesystem I should or should not use. I'll install Ubuntu 16.04, and I need to backup my data (*.couch), I know CouchDB is tail-append but some of .couch database are close 100 GB and then was wondering about my next filesystem to store those .couch files. Which one is better faster stronger? Which one cannot (should not) be used? I was thinking about zfs, xfs, btrfs... Any advice? Thanks. Max.
