error writing chaincode install package to %s

Error message

error writing chaincode install package to %s

What it means

Store.Save persists a chaincode install package to disk; when ReadWriter.WriteFile fails, the error is wrapped with 'error writing chaincode install package to %s' and returned to the caller. The package is not installed. Note the message reports ccInstallPkgFilePath while the write actually targets s.Path/ccInstallPkgFileName.

Solutions

1. Free disk space or raise the volume quota on the peer's fileSystemPath
2. Check ownership/permissions of the _lifecycle chaincodes directory
3. Retry the install command after fixing storage; save is idempotent for already-installed packageIDs
4. Inspect the wrapped inner error in the log line for the exact OS cause

Example fix

$ df -h /var/hyperledger/production   # check space
$ ls -ld /var/hyperledger/production/lifecycle/chaincodes

info, err := os.Stat(storePath)
if err != nil { return err }
if !info.IsDir() || unix.Access(storePath, unix.W_OK) != nil { return fmt.Errorf("store path %s not writable", storePath) }

packageID, err := store.Save(label, pkg)
if err != nil {
  if strings.Contains(err.Error(), "error writing chaincode install package") {
    // inspect disk space & perms, retry
  }
  return err
}

When it happens

Trigger: Calling Save(label, ccInstallPkg) after Exists() says the package is new, but the subsequent WriteFile fails due to disk full, permission denied, or I/O error.

Common situations: Disk quota/full volume on the peer; install directory permissions changed after Initialize; underlying storage (NFS volume) transiently unavailable during chaincode install via lifecycle CLI/SDK.
