[catstreet]

Hello everyone I am from Taiwan
because english is not very good
So only use GOOGLE translation
come up for help

OS Version:TrueNAS-SCALE-22.12.0
Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz
Ram:126 GiB

Disks
4 x 2Tb HDD
4 x 512Gb KLEVV CRAS C710​

Something went wrong with the settings causing
pool one of VDEV
want to ask say
Can it be removed individually
problematic VDEV
or put my STAT-HDD raidz1-0 do transfer
already tried with

your pool is damaged.
you must have all vdevs online.
you cannot remove a RAIDz vdev. you need to get at least 3 disks from raidz1-1 connected to access this pool.

your pool is mis-constructed; you need to destroy it and make it again, and then restore from backups, or start from scratch if you have no backups.
do not mix SSD and HDD disks in the way you have.
if you want to use SSD's in the same pool as HDDs, the options are to use the special devices, such are metatdata/L2ARC

additionally, raidz1 is discouraged.

looking up Taiwan, it seems that Chinese might be the correct language?

你的游泳池坏了。

你必须让所有 vdev 在线。

您不能删除 RAIDz vdev。您需要从 raidz1-1 连接至少 3 个磁盘才能访问此池。


你的游泳池构造错误；您需要销毁它并重新制作它，然后从备份中恢复，或者如果没有备份则从头开始。

不要按照您的方式混合使用 SSD 和 HDD 磁盘。

如果您想在与 HDD 相同的池中使用 SSD，可以选择使用特殊设备，例如 metatdata/L2ARC


此外，不鼓励使用 raidz1。

查找台湾，似乎中文可能是正确的语言？

Also if I'm not wrong Taiwan uses traditional chinese.

totally possible. I don't actually know the difference. simplified seems....simpler :|. it was a stab in the dark.

Or is there a way to export raidz1-0 data
Because the hard disk of raidz1-1 has been formatted

 

[catstreet]

Because currently the following raidz1-1 The hard drive has been formatted
Does it mean that it cannot be repaired
Or is there a way to export the data of raidz1-0

No, I'm sorry. As far as I know you can only try (very expensive) recovery services.

 

[artlessknave]

both vdevs must be online. if raidz1-1 is already formatted, the pool is destroyed.
if raidz1-1 doesnt exist, then raidz1-0 no longer holds any useful data. zfs data is stored striped across each vdev in the pool.

for example: mymovie.mp4 50GB might have 25GB on raidz1-0 and 25GB on raidz1-1.
if either of those vdevs is unavailable, the file is lost. this applies to the entire pool.

there are paid services to recover data, but these are in the many thousands of dollars range, and might still find nothing reconstruct-able.

you need to do some serious reading before you consider TrueNAS again. something like unraid might be better, as they are designed for the less technical and to be more flexible.
also: BACKUPS. RAID(z) is not a backup.

TrueNAS is a one trick pony, but the trick it does is VERY good, as long as you set it up correctly.
