ZFS vs XFS

We're considering building a ~16TB storage server. At the moment, we're considering both ZFS and XFS as filesystem. What are the advantages, disadvantages? What do we have to look for? Is there a third, better option?

Ext4 vs. XFS vs. Btrfs vs. ZFS for NAS

My use case: I have Ubuntu Server 18.04 installed on an M.2 SSD. I have a 4TB HDD I want to add as storage. Since it's mostly for large media files and backups, it won't be written to very often. Which filesystem do you think is best suited for this…

The XFS filesystem is broken in RHEL/CentOS 6.x - What can I do about it?

Recent versions of RHEL/CentOS (EL6) brought some interesting changes to the XFS filesystem I've depended on heavily for over a decade. I spent part of last summer chasing down an XFS sparse file situation resulting from a poorly-documented kernel…

Very strange file size (more than 600 PB) on a small filesystem

I had a file on an XFS filesystem which size was about 200 GB. It was a QCOW2 image containing a virtual disk of a KVM-driven virtual machine. Something went wrong (maybe it was some glitch of qemu-kvm, I'm not sure), the virtual machine had crashed…

Production-ready, highly reliable filesystems on Linux: ext4 ext3 XFS or JFS (or ZFS)?

The last real question I've seen on this topic is from about two years ago (is ext4 ready for production usage). In the intervening time, how has ext4 improved? XFS, JFS, and ext3 are the standby reliable choices. I've only used ext4 on recent…

How can you shrink an XFS filesystem?

I have an xfs filesystem that has some free space. Can I shrink it? I know of xfs_growfs. And there is resize2fs and resize_reiserfs. Side question: is xfs not a good filesystem choice for bulk longterm file storage?
