I just downloaded solaris. They have two versions, the split DVD that comes with two 1.2GB zipped chunks and an exe which is 1.2GB but uncompresses to the full 2.5+GB. I found some info on them here: http://www.nosltd.com/nosso.html Any idea how they achieve such great compression? Looks like they're using a proprietary algorithm and don't offer any downloads. Also looks like

Since the built in kernel doesn't have the raid10 module for some reason, I would like to custom compile a kernel that does, and install with it. How would I go about doing this? Russ

We are building an exchange cluster with two front end Outlook Web Access servers. We would like to at least have some sort of failover, and prefereably load balancing for them. The MS recommended way is to use NLB, but for various reasons that's not working with our set up. We are looking to set up a single linux server and use something like LVS to load balance/fail over the

We have a RHEL2 server that has had one of the drives in the raid array fail. I would like to do a full backup of the system before we replace the raided drive, in case the second drive decides to die during the procedure. What is the recommended way to back up a linux system? I was thinking of doing a snapshot, but the system is ext3 with no LVM. It has been suggested to hook up a usb

Is there such a filesystem available? It seems like it wouldn't be too hard to implement... Basically do things on a block by block basis. Store md5 of a block in the table, and when writing a new block, check if the md5 already exists and then point the new block to the old block. Since md5 is not guaranteed unique, might need to do a diff between the 2 blocks and if the blocks are indeed

I'm trying to use the CentOS server for windows backups. I want to use rsync to get the data over there. I downloaded cwrsync, but I'm having issues getting it to work. I keep getting: "Disconnecting: Timeout, server not responding." Has anyone seen anything like this? Here is a transcript: C:\Documents and Settings\Russ>rsync -vvvvvvv /cygdrive/c/temp/xr backup-db

I would like to set up CentOS on 4 SATA hard drives that I would like to configure in RAID10. I read somewhere that Raid10 support is in the latest kernel, but I can't seem to get anaconda to let me create it. I only see raid 0, 1, 5, and 6. Even when I tried to set up raid5 or raid1, it would not let me put the /boot partition on it, and I though that this was now possible. Is it

So I'm playing around with S3 and elasticdrive, and I create a filesystem on it with a block size larger then 4k. mkfs.xfs -b size=8k /mnt/ed5/ed0 -f This completes fine and sets up the proper filesystem. When I try to mount it, however, I get: mount /mnt/ed5/ed0 /mnt/eds35/ -o loop mount: Function not implemented looking at dmesg I get: XFS: Attempted to mount file system with

So when I couldn't get the raid10 to work, I decided to do raid5. Everything installed and looked good. I left it overnight to rebuild the array, and when I came in this morning, everything was frozen. Upon reboot, it said that 2 of the 4 devices for the raid5 array failed. Luckily, I didn't have any data on it, but how do I know that the same thing won't happen when I have

So after troubleshooting this for about a week, I was finally able to create a raid 10 device by installing the system, copying the md modules onto a floppy, and loading the raid10 module during the install. Now the problem is that I can't get it to show up in anaconda. It detects the other arrays (raid0 and raid1) fine, but the raid10 array won't show up. Looking through the logs

I'm trying to back up our svn repositories, and I found a nice little backup command line bzip's the backup and creates the md5 hash all in one: svnadmin dump --deltas /repo |bzip2 |tee dump.bz2 | md5sum >dump.md5 The problem is I need to split the backups, so this doesn't really work. Is there perhaps another way of piping things to allow for splitting of the backups?
