Using a NetApps server for MySQL databases (fwd)
by David Lee 12 Jan '04

12 Jan '04

Our MySQL person, who is not on this list, has drafted the question below. (He had earlier asked on a "mysql" list but received very little feedback.) # Currently we are using mysql-standard-4.0.12-sun-solaris2.8-sparc on a # Solaris 8 machine where the MySQL databases, MySQL binaries and MySQL # logs are stored on local discs. # # We now want to store the MySQL databases, the MySQL binaries, and the # MySQL logs on a NetApps server, and to access these filesystems from # the Solaris 8 machine using NFS. # # Are there problems with doing this? # Are people using NetApps to store the databases for MySQL? The anxieties we wish to allay with this query concern things such as locking, simultaneous access, etc. At present, there would continue to be a single front-end machine (the Solaris 8 one mentioned above). Further into the future, this might be replicated for failover (not simultaneous access), for loadsharing (simultaneous access) and/or be replaced by Redhat/Linux. Are there any known issues on these further points? Thanks in advance. -- : David Lee I.T.

thanks alot guys for clearing this up. I'll try to update my version of ntp. I really hate to upgrade my Netapp unless I HAVE to. Right now I have the device syncing with an external time source but would prefer to use our internal time server. I'll see how far I get with this. Thanks again.

Hi all NTP is a UNIX service described in RFC 1119 it is not "Linux special" I use NTP to sync two filers and I had troubles with some old versions of Ontap and NTP.

I have ntp running on my of my linux servers which acts as the time server for my network. I want to have my netapp sync to this server using ntp.

Hi Michel, This is neto from NetApp Brazil. How are you? The terminal services is not good to manage new hardware resources. 2 tips : - If you need to use Terminal Services - Workaround : Please logoff your session and login again. Now I can see the new hardware resources, the NetApp disks. - Another tip is that you can use another terminal services, for example : Pc Anywhere (not free) or UltraVNC (free) - http://sourceforge.net/projects/ultravnc . I've make tests using PC Anywhere and UltraVNC and this problems doesn't ocurr. If you need more informations or any help, please let me know.

Re: ntp time synchronization is not working

Hello, Maybe should you check if your NTP server can be upgraded to a new one. There might be a flaw in the implementation of the protocol that might prevent the Filer to correctly understand the time sync message or on the other hand, a flaw that might prevent NTP server to correctly understand the request from the Filer. I must say that I'm very surprised that a Linux NTP does not work correctly with a Filer... Indeed, we rely on a NTP server on Windows NT 4.0 which is W32Time from Microsoft, a very simple product, and I haven't got any problem synchronizing our Filers with it. Since MS is well known for their "particular" implentation of public protocols, I would not be surprised to have problems with it, which it's not the case!

I have the iSCSI protocol enabled on my filer, and I have the Microsoft iSCSI initiator downloaded and installed on my PC. From the filer, I have created a couple LUNs on my filer, I have created igroups, mapped the LUNs to the igroups, set the create_ucode option to on, and started the iSCSI service. On the Windows system, I have added the target portal, logged on, and I can see an active session. I think I have all the basics under control. What I can't seem to figure out is how the LUNs now show up as being somehow connected to my Windows computer. I'm sure I've missed something, but I can't figure out what.
