Hi,
I use the following my.cnf:
[mysqld]
innobase_data_home_dir = /opt/mysql/var/
innobase_data_file_path = ib_data1:10M
innobase_log_group_home_dir = /opt/mysql/var/
innobase_log_arch_dir = /opt/mysql/mysql/var/
set-variable = innobase_mirrored_log_groups=1
set-variable = innobase_log_files_in_group=3
set-variable = innobase_log_file_size=5M
set-variable = innobase_log_buffer_size=8M
innobase_flush_log_at_trx_commit=1
innobase_log_archive=0
set-variable = innobase_buffer_pool_size=16M
set-variable = innobase_additional_mem_pool_size=2M
set-variable = innobase_file_io_threads=4
set-variable = innobase_lock_wait_timeout=50
After first starting mysql with the start.server script innobase create the
necessary files in the /opt/mysql/var directory but than it ends up with a
memory fault.
.err:
010405 16:45:39 mysqld started
Innobase: The first specified data file /opt/mysql/var/ib_data1 did not exist:
Innobase: a new database to be created!
Innobase: Log file /opt/mysql/var/ib_logfile0 did not exist: new to be created
Innobase: Log file /opt/mysql/var/ib_logfile1 did not exist: new to be created
010405 16:45:44 mysqld ended
Restarting mysql everytimes reproduces the memory fault.
After some experiments I found that the line
innobase_log_group_home_dir = /opt/mysql/var/
causes the problem
If I start mysql (after removing all ib_files) with the following my.cnf
everthing works fine:
[mysqld]
innobase_data_home_dir = /opt/mysql/var/
innobase_data_file_path = ib_data1:10M
#innobase_log_group_home_dir = /opt/mysql/var/
#innobase_log_arch_dir = /opt/mysql/mysql/var/
#set-variable = innobase_mirrored_log_groups=1
#set-variable = innobase_log_files_in_group=3
#set-variable = innobase_log_file_size=5M
#set-variable = innobase_log_buffer_size=8M
#innobase_flush_log_at_trx_commit=1
#innobase_log_archive=0
#set-variable = innobase_buffer_pool_size=16M
#set-variable = innobase_additional_mem_pool_size=2M
#set-variable = innobase_file_io_threads=4
#set-variable = innobase_lock_wait_timeout=50
Now I again remove the ib_files and restarted mysqld with the following my.cnf
file and mysql crashes with a memory fault again.
[mysqld]
innobase_data_home_dir = /opt/mysql/var/
innobase_data_file_path = ib_data1:10M
innobase_log_group_home_dir = /opt/mysql/var/
The funny thing is, that if you initialize the innobase stuff with the '2 line'
my.cnf you can afterwards enable 'innobase_log_group_home_dir =
/opt/mysql/var/' and mysqld keeps on running.
Any idea?
