Description Problems with detecting hardware such as SCSI cards or LAN cards.
(Linux system specific)
Explanation Problems when using an ASUS PR-DL533 motherboard: Linux does not detect hardware
correctly. It is a known problem of the Linux ACPI subsystem that it does not work correctly with
some motherboards. If specifying the general acpi=off option, it is possible that the ACPI
subsystem does not detect the hardware (on-board network card, SCSI card) correctly.
Workaround Specify the following boot parameters:
acpi=oldboot pci=noacpi apm=power-off
Description If you check for potential inconsistencies between a File System Catalog (FSC) and Fast
Recovery Information (FRI) data on the corresponding FSE media, the following lines may be
present in the output of the fsecheck --fsc-media <PartitionName> command:
DUMP: FSC FRI Notes
MigSize <SizeInFSC> <SizeInFRI> MISMATCH
MigFlags <FlagsInFSC> <FlagsInFRI> MISMATCH
The MISMATCH keywords indicate inconsistencies. After you invoke the command
fsecheck --fsc-media <PartitionName> --autocorrect to solve the underlying problems, these
inconsistencies are not resolved.
Explanation Mismatches cannot be resolved using the fsecheck command. The command
fsecheck --fsc-media PartitionName --autocorrect only resolves situations
when information is missing either in the File System Catalog or on FSE media.
Workaround To solve this problem, the problematic files need to be re-migrated. Proceed as follows:
1. Put each problematic file on the migration candidate list:
fsefile --migrate FileName...
2. Trigger migration on the FSE partition that stores the problematic files:
fsefile --trigger-migration PartitionName
For more information on the fsefile command, see the fsefile man page.
