[Sks-devel] Server won't start after copy of DB

[Arnold]

Hello,

My Debian SKS-server was running very well, until this weekend.

I moved the database to an SSD hard disk and since that moment it
immediately exits after it starts.

These are the last lines of my db.log and recon.log, with debug level 100
(same result at 10 or 9):

The system is running
- Debian Stable 'Lenny' with
- Linux 2.6.32-bpo.4-686 (from the back ported archive)
- SKS-server v 1.1.0

The database is now on this partition:
- /dev/sdb13 on /srv type ext4 (rw,nosuid,nodev,user_xattr)

With the change of HD, I also moved from ext3 to ext4, which is better for
an SSD. Ext4 is also the reason to use the newer, back ported Linux kernel
(running this Linux kernel for several weeks already). The mount option
'user_xattr' was already in use for one or two weeks to accommodate
'calendar server' (Apple's open source CalDav server).

Also this weekend several packages were updated. I think I did not reboot
after installing these updates. So the move of the database to the SSD was
the first restart of the SKS-server.

  The following packages will be upgraded:
    bind9 bind9-doc bind9-host bind9utils dnsutils libbind9-50 libdns55
    libisc52 libisccc50 libisccfg50 liblwres50 libsmbclient libwbclient0
    samba samba-common samba-doc smbclient smbfs sudo swat


Here the log lines (default debug level 4) of the last working situation and
the first problem, after the copy to the new SSD.

From 2:26 to 5:10, I copied several partitions.


So, has anybody a clue why the SKS-server refuses operation? The log lines
(at debug level 10 or 100) don't help me further. Are there any known issues
with SKS and ext4 or with the last Debian update to bind, samba, etc? Any
other things I can try? (Oh, I copied the /srv/pub/sks directories again,
now with "rsync -xaX" instead of "cp -a", but with the same result...)

Please, help. TIA!
