Hammer Core Dumped on DragonFly v2.13.0.154.g481b38-DEVELOPMENT

[Siju George]

Hi,

After praying in Tongues I rebooted again :-)

Data is back safe!

Is there something special about the re boot just after a core dump?
Just wondering why this didn't come up straight the first time

Backup3                   464G   182G   282G    39%    /Backup3
/Backup3/pfs/@@-1:00002   464G   182G   282G    39%    /Backup3/mysql-baks
/Backup3/pfs/@@-1:00001   464G   182G   282G    39%    /Backup3/VM-Backup
/Backup3/pfs/@@-1:00003   464G   182G   282G    39%    /Backup3/svn-baks

/Backup3/pfs/@@-1:00005   464G   182G   282G    39%    /Backup3/Data

v# pwd
/Backup3/mysql-baks/agsrv
# undo -i 2011-11-11-all.sql.bz2
2011-11-11-all.sql.bz2: ITERATE ENTIRE HISTORY
        0x000000010a549b40 11-Nov-2011 18:30:45

earlier it was

> # undo -i 2011-11-11-all.sql.bz2
> 2011-11-11-all.sql.bz2: ITERATE ENTIRE HISTORY: Inappropriate ioctl for device

Could some one give the explanation?

Thanks :-)
