Hi Heikki,
Still only one process with ps -fA. And mysql doesn't want to start normally.
This morning I tried by deleting innodb files (ibdata1,ib_logfile0, ib_logfile1), and it didn't succeed in recreating them.
I just tried once again now and everything is fine, mysql starts and recreates the files.
Thank you very much for your help!
Just for information: if I had an innodb table (I'm thinking about it), the data would have been in there.
Any recovery method? Or I would have had to delete the files and restore the data from backup?
Anyway, thanks a lot! Melanie

Mel,
do
ps -fA
Do you see more mysqld processes?
If the ibdata1 file stays locked even though there is no mysqld process, then this is a bug in Linux.
If you do not use InnoDB, you can delete ibdata1 and ib_logfiles.
Best regards,
Heikki

Aihe: Re: mysql crash - innodb not starting
I did ps -aux I see one mysqld running (mine, launched with --skip-innodb). I shut it down. ps -aux: nothing I tried to start it again, doesn't work.
As it is running on a machine managed by the system service I went to see them after shutting it down again, they have no mysql process running. (still using ps-aux, but as root on that machine)
From that I think it means I don't have any mysql running there, and I still get that error 11.
Or is there an other to see if a file is already used by a mysql process?
Do you think replacing the ibdata1 file by an empty file is possible?
Or doing a new install , copying my isam tables from the data directory and not touching the innodb files?
Doing a new install and setting up my tables (isam) with a backup dump is better?
I would prefer to repair the existing installation, but have no idea where to begin....
Thanks a lot for your time.

Hi!
Error 11 means that you already have a mysqld process running on the same files.

Subject: mysql crash - innodb not starting
Hi, I just have a crash of my mysql 4.1.5 .(the machine where it was running just shutdown)
Tried to restart it, and problem with innodb:
050303 11:58:46 [WARNING] Asked for 196608 thread stack, but got 126976
InnoDB: Unable to lock ./ibdata1, error: 11InnoDB: Error in opening
./ibdata1
050303 11:58:46 InnoDB: Operating system error number 11 in a file
operation.
InnoDB: Error number 11 means 'Resource temporarily unavailable'.
InnoDB: See also section 13.2 at http://www.innodb.com/ibman.php
InnoDB: about operating system error numbers.
InnoDB: Could not open or create data files.
InnoDB: If you tried to add new data files, and it failed here,
InnoDB: you should now edit innodb_data_file_path in my.cnf back
InnoDB: to what it was, and remove the new ibdata files InnoDB created
InnoDB: in this failed attempt. InnoDB only wrote those files full of
InnoDB: zeros, but did not yet use them in any way. But be careful: do not
InnoDB: remove old data files which contain your precious data!
050303 11:58:46 [ERROR] Can't init databases
050303 11:58:46 [ERROR] Aborting
050303 11:58:46 [NOTE] ./bin/mysqld: Shutdown complete
I'm sure I already saw that kind of problem, tried to go through the list
but didn't find the thread again. In addition I'm not very familiar with
that kind of thing.
I don't use innodb at all, only myisam, so I was able to restart with
--skip-innodb.
About the error code "ressource unavailable" I tried later on no difference,
the file ibdata1 is there with adequate permissions, I don't think that I
have a my.cnf...
To sum up I have no idea what to do, and I'm not a system guru! My first ideas: - removing the ibdata1 file and recreating an empty one - I saw a force-recovery option but have no idea how it works
Hope somebody here can help me.... Thanks a lot
