Troubleshooting ZFS – Common Issues and How to Fix Them

Does ZFS suffer the equivalent of the dreaded btrfs ENOSPC?
nelox•5mo ago
ZFS can hit “No space left on device” (ENOSPC) errors if the pool fills up. But unlike btrfs’s infamous ENOSPC woes, ZFS was designed to handle these situations much more gracefully. ZFS actually keeps a bit of “slop space” reserved. So, as you approach full, it stops writes early and gives you a chance to clean things up, instead of running into unpredictable issues or impossible snapshot removals like btrfs sometimes does. You can even tweak how much safety space ZFS reserves, though most users don’t need to touch it.

[https://news.ycombinator.com/item?id=11696657]

When you run out of space in ZFS, you get a clear error for write attempts, but the system doesn’t end up fragmented beyond repair or force you into tricky multi-step recovery processes. Freeing up space (by deleting files or snapshots, or expanding the pool) typically makes things happy again.

I thought Btrfs includes a fix by reserving about half a gig up front for that purpose/prevention?

damn i thought it was klarna, the fabled burrito borrowing service. "wow they're self-hosting zfs? fascinating..."
totetsu•5mo ago
What about .. you mounted your system disk and an external drive on another system and now you put it back in your laptop it won’t boot because some pool thing got changed.
anotherhue•5mo ago
You might have changed the hostid, and it refuses to mount it as a safety precaution. IIRC it's a quick fix.

E39M5S62•5mo ago
Use ZFSBootMenu, it automatically corrects hostid issues each boot by passing spl.spl_hostid to the kernel, matching the value set on the pool itself.

Remote send/recv can be frustrating due to the need for root.

It can be helpful to remember that while less efficient, for scenarios where ssh as root is a no-go you can ship snapshot syncs (including incremental ones) as files:

    zfs send [...] tank > tank.zfssnap
    cat tank.zfssnap | zfs recv [...] bank

>It can be helpful to remember that while less efficient, for scenarios where ssh as root is a no-go you can ship snapshot syncs (including incremental ones) as files:

This capability can also be extremely helpful for bootstrapping a big pool sync from a site with mediocre WAN (very common in many places, particularly when it comes to upload vs download). Plenty of individuals or orgs may be characterized by having quite a sizable amount of data accumulated by this point, but they're not generating new data at a prodigious clip. So if you can get the initial replication done, ongoing syncing from there can be possible over a fairly narrow pipe.

Latency might not be quite the best, but sometimes the greatest bandwidth to be had is a big fat drive or set of them in the trunk of a car :)

You can delegate with zfs allow. Relevant permissions are send, receive, maybe create?

aborsy•5mo ago
I think ZFS send -w should be default. You enter a flag if you want to send plaintext.

Also something like sanoid needs to be built in to ZFS. Find out all newer snapshots at source by zfs list and send the first and last.

Nice website btw. Does anyone know what tools are used to build this website?

What if you need to delete 200TB of data, and you forgot to put your metadata on an SSD?
GauntletWizard•5mo ago
You can add a metadata device to the pool at any time - it's probably faster to add that pool and wait for it to populate than to delete all that data with metadata on spinning rust.
tinco•5mo ago
It was a while ago. I think I needed to move the data one directory at a time to get it to move the metadata to the SSD 's.

Since that still would take months I think I simply waited for the next upgrade and moved all the data to a new pool. And deleted the old one.
