Hi,

As a result of my last advfs crash, I did a verify on all of my AdvFS
partitions and found that almost all of them contained errors like:

Checking tag directories ...
check_tagdir_page: bad allocated tag count
    set tag: -2.0 (0xfffffffe.0x00000000)
    tag: 1.32769 (0x00000001.0x00008001)
    tag directory page: 18
    real count: 957, expected count: 954
check_tagdir_page: bad free tag count
    set tag: -2.0 (0xfffffffe.0x00000000)
    tag: 1.32769 (0x00000001.0x00008001)
    tag directory page: 18
    real count: 65, expected count: 68

The root partition additionally has:

Checking tag directories ...
check_tagdir_page: in-use on-disk tag does not have matching in-mem tag hdr
    set tag: 1.32769 (0x00000001.0x00008001)
    tag: 489.33517 (0x000001e9.0x000082ed)
    tag directory page: 0
    tag map entry: 489
    seqNo: 0x82ed (33517)
    vdIndex: 1
    bfMCId (page.cell): 83.4
check_tagdir_page: in-use on-disk tag does not have matching in-mem tag hdr
    set tag: 1.32769 (0x00000001.0x00008001)
    tag: 840.33611 (0x00000348.0x0000834b)
    tag directory page: 0
    tag map entry: 840
    seqNo: 0x834b (33611)
    vdIndex: 1
    bfMCId (page.cell): 128.22

Questions:

    * Should I be worried?

    * /sbin/advfs/verify did not fix these errors even with the -f
      and -d flags. How can I fix them without re-building the domain
      and restoring the files from tape?

    * Could these errors have cause my last crash (as described in my
      previous posting)

Thanks a lot -- Tom
