error while deleting the dir: %s

Error message

error while deleting the dir: %s

What it means

initSnapshotDir wraps the os.RemoveAll error for the in-progress snapshots directory (SnapshotsTempDirPath under the configured root). Before serving snapshots, Fabric clears any stale in-progress snapshot data; a failed delete (permissions, busy mount, I/O error) produces this wrapped error.

Solutions

  1. Check the wrapped underlying error in the peer log (permission denied vs read-only vs I/O)
  2. Fix ownership/permissions: chown/chmod the snapshots rootDir for the peer's OS user
  3. Remount the volume read-write if it is mounted read-only
  4. Manually remove <rootDir>/inProgressSnapshots (or completedSnapshots) and restart

Example fix

// before: error while deleting the dir: /var/hyperledger/production/snapshots/inProgressSnapshots: permission denied
// after:
# chown -R fabric:fabric /var/hyperledger/production/snapshots
# peer node start
Defensive patterns

Strategy: validation

Validate before calling

inProgress := filepath.Join(rootDir, "inProgressSnapshots")
if info, err := os.Stat(inProgress); err == nil && info.IsDir() {
    if err := os.Chmod(inProgress, 0o755); err != nil {
        return fmt.Errorf("cannot manage snapshots dir %s: %v", inProgress, err)
    }
}

Prevention

When it happens

Trigger: Peer startup (NewProvider -> initSnapshotDir) when os.RemoveAll(<rootDir>/inProgressSnapshots) fails, e.g. read-only mount, root-owned files from a previous run as another user, or filesystem I/O error.

Common situations: Container volume mounted read-only, snapshots dir created by root but peer now runs as non-root user, permission-changed directories, or corrupted filesystem.
