Can you use ddrescue to copy the data off the "unhealthy third disk" to another good 'donor' drive, that can then be used for the resilvering process without the timeouts problem (assuming timeouts are drive not controller/cable related)?ddrescue will continue after retry with all uncopied data, not copying stuff already copied.
Startet that, but the question here is how to reinsert the disk copy
into the pool, since the devices are recorded in the (checksum protected)
label. Will zpool export/zpool import fix that when the defect disk is
pulled and the donor has the wrong path/phys_path/devid/fru (compared to
the copied label) ?
