But it's totally different than corruption in other filesystems. People are acting like upgrading to ZFS 2.2.0 ate all their data like XFS used to back in the bad old days. I remember once the power went out at my house, and the entire XFS filesystem was irreparably damaged. This bug is super hard to trigger, and has roots back to 2006 and only surfaced with a recent coreutils update. Yet there are numerous posts in the past few days verging on hysteria. I myself was very worried until I saw posts like the grand parent comment or the linked GitHub issues. I don't believe there's actually a campaign of ZFS haters sitting around in a storeroom somewhere posting to phoronix and HN, but it does feel like a lot of strongly held opinions are being unleashed now that ZFS had this bug. I'm pretty sure ZFS has been abused a lot - ten years ago I was helping test petabyte scale ZFS clusters, doing tons of concurrent IO and such. I'm pretty sure Sun and Oracle tested the crap out of it.

ZFS wouldn't even have a hundredth of the testing of real-world use ext3/ext4 in hours. The large scale deployments of ext3/ext4 dwarf the usage of ZFS.

This is Linux local bias. There is more to Unix than Linux. Back around 2001 when work on ZFS began, I very strongly suspect that there were several orders of magnitude more storage on ZFS on Solaris in datacentres around the world than there were on all Linux filesystems combined. Just because you are more familiar with the FOSS tool doesn't mean that it's more mature or more widely used or more deployed in production.

    I would -very- strongly imagine it the other way. I guess we'll never know.

      I worked at a company that shipped petabytes of ZFS storage for years and years. Think 42u racks with 60 drive JBODs. Hundreds of these. Hundreds. And they were a very small company. Can you imagine the scale Sun and Oracle shipped hardware at? Was there any linux based hardware company operating at the same scale? I don’t think we had any customers request ext4 bulk data storage. OS drives sure. Everything else was ZFS. Or weirder proprietary filesystems!

        Yeah, that GPFS was real pita, i'm not talking about size comparison issues. I'm talking about runtime in the field. You simply can't begin to understand the amount of shitty iot and android devices that exist.

      See the earlier comment to you. I think you have this 100% backwards. I heard similar comments to yours inside some large Linux vendors, too, and I think they betray a profound misunderstanding about the nature of large-scale Unix deployments over the years. FOSS Unix is recent and mostly small-scale and transient deployments of containers, not long-term storage... but before that, there were decades of vast scale commercial Unix systems, which dwarf the FOSS stuff.

        How many zfs systems you think are running right now, all hours combined compared to linux ext filesystems ?

  ZFS and ext4 is so completely different on a fundamental level that there is zero reason comparing them, it just shows your "expertise" on the topic..

    I dont think it takes expertise to do basic math. But aint no value in ego measuring online.
