- Hello,
- After christmas we found that our 4D-220VGX had crashed in a mysterious way:
- many programs of the OS could not be found any more, we had to reload
- the root partition from the last backup. In SYSLOG there were the following
- messages:
- Dec 27 03:13:19 gt unix: WARNING: dma_map: address not word aligned
- Dec 27 03:13:19 gt unix: sc0,1,0: cmd=0x28 disconnected on non-word boundary (ad
- dr=C046AE4F, 0x0 left)
- Dec 27 03:13:21 gt unix: . Resetting SCSI bus
- Dec 27 03:13:21 gt unix: dks0d3s0 (/usr): retrying request
- Dec 27 03:13:21 gt unix: dks0d1s6 (/usr/amandus): retrying request
-
- (repeated several times) and
-
- Dec 27 05:02:12 gt unix: dks0d1s0 (/): Directory 13 is corrupted (4d)

- (also with some other numbers instead of 19,20)
-
- After restoring the backup everything worked just fine. However, a few
- minutes ago I saw
- Jan 1 05:00:15 gt unix: dks0d1s6 (/usr/amandus): inum: 1724 illegal number of i
- ndirect extents
- Jan 1 05:00:15 gt unix:
- Jan 1 05:00:16 gt unix: dks0d1s6 (/usr/amandus): inum: 1725 illegal number of i
- ndirect extents
-
- in SYSLOG. Is this just a sign of the disk going bad (I admit it's no SGI disk,
- but has workes flawlessly for at least 3 years now) or did we
- inadvertently make some configuration or software error ?
-
- Thanks very much for any hints,
-
