• Problem Slow speeds data transfer after 10 seconds or so · Reddit · 2026-04-10

  Hi, everyone. I'm running a baremetal TrueNAS Scale installation and I recently bought a 2.5Gb NIC card + switches for big data transfers for RAW video files and Log footage. The thing is that I get a considerable speed downgrade (around 16MB/s) after the first seconds running a…

• Problem Import pool causes kernel panic, TrueNAS 25.10.0.1 ZFS bug/failure? · Reddit · 2025-12-22

  My RAIDZ-2 pool of 6 x 14 TB HDDs is currently in a state where it can only be imported as read-only. On Saturday morning at 4am a cron job attempted to run a SMART test and the server never came back alive. I was out of town but when I woke up in the morning, I received alerts…

• Mention Please don't hate, but will CORE 13.0-U6.8 be able to mount a pool created under SCALE 25.10.0.1? I want to go back. · Reddit · 2026-01-24

  I'm not loving scale. It takes 3 minutes to boot up. The dashboard widgets are flakey. Transfer rates top out at 70% of what they did under core, which was consistently bottlenecked by the 10 gigabit network link.

• Mention Slow speeds transferring data between datasets · Reddit · 2026-01-20

  Hello, I mentioned in a previous post that I messed up by creating multiple datasets for my media rather than one dataset and multiple sub-directories. I’ve just started moving everything back into the same dataset and I’ve noticed transfer speeds 3-4 times slower than usual. I…

• Mention Extremely bad disk performance · Reddit · 2025-12-21

  Hey! My read/write speeds and IO performance is terrible on a newly built setup. When using fio I get “write: IOPS=36, BW=37.5MiB/s” on sequential write and “read: IOPS=27, BW=28.5MiB/s“ on sequential read with multiple streams. When scrubbing, it takes about 10-15 days. My setu…

• Mention FreeIPA / TrueNAS SCALE 25.10.0.1 / GUI Login Possible with IPA user? · Reddit · 2025-12-18

  Hi, I'm struggling here and finding the documentation entirely unhelpful. Can someone tell me if it's possible to permit a user account in FreeIPA to login to the TrueNAS Web UI? I've setup FreeIPA and I see that I have exactly one DS Group listed in Groups / Privileges, showing…

• Mention pool suspended after io failure. only importable as readonly, truenas will not boot with more than any 2 out of 4 drives... · Reddit · 2025-12-15

  Hi, yesterday I received alert from truenas scale (after 140 days of worryfree uptime): Pool arc state is SUSPENDED: One or more devices are faulted in response to IO failures. All data were still there and were available, after quick googling and gemining, I powered down the sy…

• Mention Seagate drives random spinups without apparent reason · Reddit · 2025-12-14

  Hi, I just added a second truenas system into my home lab as a backup to replace my DS220j Synology because of performance issues and missing flexibility. Like on my main system, I want that the HP Elitedesk G3 (SFF) runs all apps from an SSD and just spins up the HDDs (Seagate…
