X_STORAGE_PUT_FAILED
Means
the object could not be written
Typical cause
the disk refused a put() or copy() — a root this process cannot write (EACCES), a full or read-only volume (ENOSPC, EROFS), or a provider that answered the write with a refusal. It surfaced as a bare filesystem Error or a bare S3Error; nothing was stored, and any existing object at the key is untouched.
Fix
local: ls -ld <root> && df -h <root> with the disk's own root, which the error prints. s3: aws s3api get-bucket-policy --bucket <bucket>
