I am running RHDS in a VM, but would like to store the data and logs on a separate volume, that is on a SAN. The partition is ext4fs on /sdb1 and is mounted as /data.
I tried many variations of the different approaches described here. First, after a fresh install of RHDS, before I created any instances, I created the folders on /data and linked to them from /var, as follows:
mkdir /data/lib mkdir /data/log mkdir /data/lib/dirsrv mkdir /data/log/dirsrv rmdir /var/log/dirsrv rmdir /var/lib/dirsrv ln -s /data/lib/dirsrv/ /var/lib/ ln -s /data/log/dirsrv/ /var/log/
When I create an instance (named esx02vm01) of the directory, I get this error:
[02/May/2013:09:51:45 -0400] - /etc/dirsrv/slapd-esx02vm01/dse.ldif: nsslapd-errorlog: Cannot open errorlog file "/var/log/dirsrv/slapd-esx02vm01/errors", errors cannot be logged. Exiting....
I thought RHDS might be having trouble with the symbolic links. In my second attempt, I instantiated with files in the default locations. After confirming the directory was working, I shut it down. Then I moved the instance folders under /var/lib and /var/log over to the /data folder and modified the dse.ldif file for that instance to point to the new folder locations, as follows:
mkdir /data/lib mkdir /data/log mkdir /data/lib/dirsrv mkdir /data/log/dirsrv cp -r --preserve=all /var/lib/dirsrv/slapd-esx02vm01 /data/lib/dirsrv/ cp -r --preserve=all /var/log/dirsrv/slapd-esx02vm01 /data/log/dirsrv/ vi /etc/dirsrv/slapd-esx02vm01/dse.ldif * replace all /var/lib/dirsrv/slapd-esx02vm01 with /data/lib/dirsrv/slapd-esx02vm01* :%s/\/var\/lib\/dirsrv\/slapd-esx02vm01\//\/data\/lib\/dirsrv\/slapd-esx02vm01\//g * (6 substitutions on 6 lines) * replace all /var/log/dirsrv/slapd-esx02vm01 with /data/log/dirsrv/slapd-esx02vm01 :%s/\/var\/log\/dirsrv\/slapd-esx02vm01\//\/data\/log\/dirsrv\/slapd-esx02vm01\//g * (4 substitutions on 4 lines) :qw mv /var/lib/dirsrv/slapd-esx02vm01 /var/lib/dirsrv/old-slapd-esx02vm01 mv /var/log/dirsrv/slapd-esx02vm01 /var/log/dirsrv/old-slapd-esx02vm01 service dirsrv start
I got the same error attempting to start the directory:
Starting dirsrv: esx02vm01...[03/May/2013:08:56:00 -0400] - /etc/dirsrv/slapd-esx02vm01/dse.ldif: nsslapd-errorlog: Cannot open errorlog file "/data/log/dirsrv/slapd-esx02vm01/errors", errors cannot be logged. Exiting....
Then, I moved the error file back to the original location, so just the database file was on /data. These errors where logged when the directory is started:
[03/May/2013:09:17:17 -0400] - 389-Directory/126.96.36.199 B2013.100.2247 starting up [03/May/2013:09:17:17 -0400] - mkdir_p : error -5950 (File not found.) [03/May/2013:09:17:17 -0400] - Can't start because the database directory "/data/lib/dirsrv/slapd-esx02vm01/db" either doesn't exist, or is not accessible [03/May/2013:09:17:17 -0400] - start: Failed to init database, err=-1 Unknown error: -1
In each case, I confirmed that the reported directories and files exist, and that they have the same ownership and permissions as the original directories and files. When I created the instance, I ran setup-ds-admin.pl as root, using the account rhds for the instance. I created the rhds user with the command:
useradd -M rhds
What is the proper way to relocate the databases for an instance of Red Hat Directory Server?
