# 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>`
