Migrated our build server array from ext4+mdadm to ZFS on Linux six months ago. Here’s what I learned. Why ZFS Checksumming catches silent data corruption (we found 14 affected files on the old array) Snapshots are cheap and instant (100ms for a 10TB dataset) Compression often makes things faster — less I/O, more CPU Send/receive for efficient replication No separate mdadm/LVM layer to debug Pool design For the build server, 6 x 4TB NVMe in RAIDZ2: ...
