Back to this topic, since I cannot touch snapshots I thought I could simply remove the corrupt files after the last snapshot, so the next incremental backup will notice the difference (i.e. no file) and overwrite the corrupt-and-removed files with valid ones. This was the plan. However, while checking for corrupt files, "find" stops at some directory with "fts_read: Not a directory": find . -exec md5 {} \; > /home/xxx/md5_out 2> /home/xxx/md5_err & tail /home/xxx/md5_err ... md5: ./.zfs/snapshot/20100323081201/Bazsi/Projects/Java Test Client/java_test_client/lib/xxx/weblogic.jar: Input/output error md5: ./.zfs/snapshot/20100323081201/@Cache (Bazsi)/BMWi SP/Publikationen/PDF-Broschâ–’ren/Nexxt.pdf: Input/output error find: fts_read: Not a directory What does this error mean? I cannot even "scan" the ZFS file system anymore? Is there any "fsck" for ZFS? Cheers, B.
