To replace the HDDs in my primary backup RAID5 enclosure, I ran a duplicacy copy to a single HDD configured with erasure encoding, successfully check -chunks, replaced the RAID5 HDDs, then copied the single HDD storage back to the RAID5. The copy operation succeeded, but with this warning:
2026-02-17 23:48:08.118 WARN CHUNK_ERASURECODE Recovering a 13837396 byte chunk from 2767480 byte shards: ****-*-
A subsequent check -chunks of the RAID5 succeeded. The storage contains about 1M chunks. I normally used the single HDD for a monthly cold backup that I keep offline.
Does the message mean that the chunk on the single HDD was recovered and re-written? If not, is there a procedure to correct the chunk on the HDD?
