Yes, I’ve been missing for a few weeks. Caught a bad case of Life. Here’s some OpenZFS Mastery.
ZFS advocates claim that ZFS is immune to these arbitrary limits, but that’s not quite true. ZFS store most of its values in 128-bit variables. One directory can have 248 files, of up to 16 exabytes each. A single pool can be up to 256 zettabytes, or 278 bytes. A storage pool can contain up to 264 devices, and a single host can have up to 264 storage pools. File and directory names can be up to 1023 ASCII characters.
The good news is, we will not live long enough to hit these limits. The bad news is, today’s sysadmins have all the expertise in migrating between filesystems. When technology hits ZFS’ limits, those poor people won’t be accustomed to migrating between filesystems. Fortunately, they’ll have a few lingering but ongoing FAT/UFS/extfs rollovers for practice.
