Failure to replicate degraded pool

[diggerydoo]

It seemingly copied 700 out of the 800 gigs to the new pool but gave the error

[EFAULT] warning: cannot send Input/output error cannot receive resume stream: checksum mismatch or incomplete stream. Partially received snapshot is saved. A resuming stream can be generated on the sending system by running: zfs send -t

It's always helpful to list your hardware and pool configuration, like the forum rules request.

Plus, this command on the source would be useful: zpool status

 

[diggerydoo]

the pool is made up of two 500gb drives and one 850gb drive
Hardware is an old amd athlon x64

Your source pool is basically lost.

It may be possible that their are cable, connector or power supply issues that affected your data disks. Further, an expert might be able to determine if the failures are in snapshots and potentially your live data could be good. But, that is beyond what I can assist with remotely. Perhaps someone else can step in.


A well managed TrueNAS server will have ZFS scrubs setup perhaps twice a month, as well as regular SMART tests. Plus notifications enabled to let the administrator know about failures while they are still manageable.


Good luck.
