Hello I'm willing to change my dedicated server hosting provider, and transfer my existing server to the new one. I don't have kvm access, but both servers are centos5.2 I can boot a network image that is debian based and have access to the disk. Then I tried to rsync -a my first server to the destination host, but it was not reachable from the network (I modified /etc/fstab and

Hi All, we are using Red Hat 2.1 Kernel e38 along with MSA 1000. ocfs version being used is $ rpm -qa | grep ocfs ocfs-tools-1.0.10-1 ocfs-2.4.9-e-enterprise-1.0.12-1 ocfs-support-1.0.10-1 Database Version is 9.2.0.5 However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete. We initially assumed RAC is

If it''s of interest, I''ve written up some articles on my experiences of building a ZFS NAS box which you can read here: http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/ I used CIFS to share the filesystems, but it will be a simple matter to use NFS instead: issue the command ''zfs set sharenfs=on pool/filesystem'' instead of ''zfs set

I am starting to see a few issues with OCFS and 9.2.0.3 RAC on redHat Linux AS 2.1. Wondering if there is anyone out there experiencing similar issues... a few pointers to the issues.. 1. OCFS read/write performance is way lower than a read/write to a raw device.. i can give you some comparison numbers.. 2. Writes to shared disk with ocfs would get locked up by one server.. it doesnt have to

Experts, We've just migrated from samba 2.2.8a to samba 3.0.20b in a very large corporate environment. Everything was really fine in our lab, but we began experiment serious load problems on the productive servers the morning after the procedure took place. I'll try (briefly) to describe the characteristics of the scenario: Resources: Old Environment: Hardware:
