Hi all
I have installed a new server with 77 2TB drives in 11 7-drive RAIDz2 VDEVs,
all on WD Black drives. Now, it seems two of these drives were bad, one of them
had a bunch of errors, the other was very slow. After zfs offlining these and
then zfs replacing them with online spares, resilver ended and I thought it'd
be ok. Appearently not. Albeit the resilver succeeds, the pool status is still
degraded. A test with iozone also shows that the two degraded VDEVs are not
used (much) during the test. See below for zpool -xv output.
I have done a few test on another system, and it showed, with raidz2 with a
spare, removing one drive, waiting for it to resilver, same degraded status.
zpool clear doesn't help. Removing another drive (not the spare) leaves it in
the same degraded status. Removing a third (which should work, since the spare
is in action) faults the pool.
Can someone help me how to fix this, or should I file a bug about this?

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er
et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av
idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og
relevante synonymer på norsk.
