Index corruption
Hi all,
We are running 2.0.22 under FreeBSD 4.5. This morning my
indexes got corrupted in an interesting manner, so that
the directory believed it had a record which didn't actually
exist.
I found one other case rather like it in the archives, but
no real explanation.
I tried to add a very simple posixAccount record:
dn: uid=chris3,dc=au,dc=cordoors,dc=com
objectClass: posixAccount
uidNumber: 1946
gidNumber: 400
homeDirectory: /usr/users/chris
loginShell: /bin/tcsh
gecos: Chris Robertson
cn: Chris Robertson
uid: chris3
userPassword: x
and the add failed with a "record already exists" message.
Tried to delete the DN, and got the following message:
Delete Result: Unknown error (80)
Additional info: DN index delete failed
I tried adding a similar record with uid=chris4, and
had no problems adding it or deleting it again.
I dumped the directory with slapcat, and the uid=chris3
record definitely didn't exist. I shut down slapd
and re-made the indexes; no change. I physically
removed the indexes and re-made them; no change.
I deleteled almost every record from the directory and
re-made the indexes; no change.
The only thing that worked was removing the whole damn
directory and re-creating it from scratch with slapadd.
Can anyone shed any light on this? I'm not aware of
anything out of the ordinary happening around the time
the indexes got munched.
