I need a cluster-safe filesystem for a SAN shared storage in Slackware. Red Hat's GFS is the best/only solution?Given GFS support in a custom kernel, what about tools (mkfs,mount...)?
View 14 RepliesI am working on the beginning of implementing a two-node cluster with shared storage (GFS) and IP address. Both machines are virtual on VMware ESX 3.5, that should not make a difference, but that is the background.current status is that I have a single node cluster built with only the IP address configured within the cluster. The issue that I am having is that I have configured a service to contain only the IP address resource, however, when I go into cluster management that "service" does not register. As such, I cannot bring it online, ping it, etc. below is my cluster.conf configuration:
<?xml version="1.0"?>

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...
Have many computers at works. Not always on as students works on it from time to time. I already have a nfs server for files, but there's plenty of disk space on workstations. I wanna make use of it as a "performance booster".Which distributed file system should i use ? Looked for Plan 9 fs, but seems a bit new and "complicated" for me.
View 2 Replies View RelatedI trying to create a Cluster Linux with two servers and one storage, I have mounted some filesystems in both servers, but, when I create a file on server (1), I don't see the file on server (2).
Is that a problem with the linux or storage configuration ?.
Can ANYONE point me in the right direction on how to use storage on multiple servers as a single cluster?I thought storage cluster was for that but, after much googling, and even more help from here, I don't think that achieves my goal. My goal is to have multiple servers share a file system, to act as somewhat of a network raid, so if node-A goes down the files are available on other nodes, and hopefully so when the capacity of the nodes are reached I can add nodes to expand the "cluster".

I'm having some trouble configuring clustering in a 2-node cluster, with no shared FS. Application is video streaming, so outbound traffic only...The cluster is generally ok - if I kill -9 one of the resource-applications, the failover works as expected. But it does not failover when I disconnect the power from the service owning node (simulating a hardware failure). clustat on the remaining node shows that the powered-down node has status "Offline", so it knows the node is not responding, but the remaining node does not become the owner, nor start up the cluster services/resource-applications. eth0 on each node is connected via a crossover cable for heartbeat, etc. Each eth1 connects to a switch.

I have configured the RHEL cluster suite in RHEL 5.3 64 bit, I have formatted a storage 100 GB LVM with GFS2 filesystem with lock_dlm protocol default journel I have used 8 I have also added this filesystem in cluster resource in GFS resource option, all work fine cluster is able to remount this GFS2 LVM on another node in time of failover. But when I was checking cluster configuration file (/etc/cluster/cluster.conf) in resource syntex it was showing fs_type=gfs so my query is if it uses fs_type=gfs then is it also mount my formatted gfs2 lvm as gfs filesystem in my cluster node rather then gfs2 filesystem. Also how do i check that mounted filesystem is gfs or gfs2, Please clear my doubt.
View 4 Replies View RelatedI have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
View 3 Replies View RelatedInitially when I shrunk my NTFS Windows partition to install Fedora 11 I underestimated how much space I'd need for Fedora. Now that I'm using it as my primary operating system I have wasted space in the form of spare space on my NTFS partition. I was just wandering how safe it is to shrink this partition and move the free space to my /home partition using gparted on Linux? This would probably involve having to shift things towards the beginning of the drive as the Windows partition is at the beginning and the /home directory is at the end. Would I need to use a LiveCD to do this since it's meddling with an active operating system? I know I should back up the data, but is it quite safe to do it despite gparted in all likelihood having to move data from block to block across the drive?

View 4 Replies View RelatedI am planning to build a server in future. That will be a computer with GNU. It will be a router and file server. It will get the VPN-Internet and share it with all the PCs connected to LAN. There will be Samba for file sharing. And I'm thinking that if I just share some directory on that server with Samba, it will be possible to get access to that dir from VPN. So it's not very safe to do that. Is it possible to prevent access to Samba dir from VPN connection?
View 7 Replies View RelatedI'm planning on setting up a home file server. I was wondering what platform would be recommended for something like this. The server would be used mainly for media storage which would be shared between an HTPC and a couple desktops and laptops. I was thinking of just getting whatever motherboard had the most SATA headers on it (which currently seems to be something P55-based) and setting up a RAID5 fakeraid with some 1.5 or 2TB drives and the OS in RAID1 with whatever drives I have laying around. It there anything flawed with this approach? P55 boards with 10 SATA headers are currently upwards of $200, which is kind of pricey. Is there a more economical route that I should consider? Also, are there any known problems with setting up a fakeraid like this using certain motherboard's SATA controllers?
View 4 Replies View RelatedIve been asked to investigate presenting the same SAN LUN to two or more RHEL5 hosts. The hosts are providing independent applications so theyre not clusters from an application perspective. The shared storage location would be used as a common area for imports/exports. Were hoping to reduce file transfer times between the hosts by eliminating the need to copy the files between two storage locations. Some of our hosts run Advanced Server and some are standard. Is there a file system that I can use that will allow multi-host access without running advanced server with clustering services on all hosts?
View 2 Replies View RelatedI am going to install Oracle RAC on two Servers, With shared SAN storage (Servers and Storage is IBM) OS = RHEL 5u5 x64 bit
And we used multipathing mechanism and created multipathing devices. i.e. /dev/mapper/mpath1. Then I created raw device /dev/raw/raw1 of this /dev/mapper/mpath1 Block device as per pre-reqs for Oracle Cluster. Every thing looks good, But we faced the performance issue as under.
when we run command :
#dd if=/dev/zero of=/dev/mapper/mpath1 bs=1024 count=1000
the writing rate is approx. 34 MB/s
But If we run command
#dd if=/dev/zero of=/dev/raw/raw1 bs=1024 count=1000
the writing rate is very slow like 253 KB/s
I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.
has anyone been able to connect a Linux VPN client to a safe@office 500 using pre-shared keys?From windows, I can establish a IPSec/L2TP(also PSK) connection with no issues(No third party software. Just created a new connection in XP).I have tried using StrongSwan and xl2tpd on Karmic without success.PPPd never gets launched. To me it seems like this should work given I can create a vpn connection directly from WinXP without installing any checkpoint clients.

(I did a full install from the DVD, not deselecting anything, and when I upgraded to -current, I also did the same.)
Ark said:

ark: error while loading shared libraries: liblzma.so.0: cannot open shared object file: No such file or directory
but I managed to fix that one by commenting out 'aaa_elflibs' in /etc/slackpkg/blacklist (on a recommendation from #slackware), and running slackpkg upgrade-all again, but that's the only one (afaik) that was fixed. Ark still doesn't work, but it doesn't show that error anymore. When I run it, a box pops up that says "Unable to find Ark's KPart component, please check your installation."
Kate still says:

Now, konsole, firefox, and Chromium's errors are a little different.
Konsole:

again, I am completely baffled here, as I had kate, konsole and ark running before I upgraded to -current.
I am running a dual boot system with Win7 on /dev/sda and Ubuntu 10.10 on /dev/sdb
I also have a 250 GB disk I use for storing backup data, /dev/sdc
The two logical partitions on /dev/sdc (/dev/sdc2 and /dev/sdc5) each take up 2.86 GB and I would like to free up that space if possible.
Since the filesystem on /dev/sdc doesn't have an OS on it, does it still require that those two logical partitions exist?
For example we have a PC with Linux and, let's say, ext4. It is connected to another PC with Linux and Samba-shared dir.First PC mounted shared dir of the second one. So it's in the filesystem, for example in "/mnt/000/". What will happen if I unplug the net cable from first PC? Will ext4 on the first PC crash so I'll have to perform fsck? I know that hot unpluging of mounted HDD probably will make filesystem read-only available and generally damaged.
View 1 Replies View RelatedWhat is the current state of NFS failover (i.e. setting up two server with shared storage, with automatic failover if one fails?) I've seen a cookbook, but no details that would let me assess how well it works. There are lots of complex issues with data consistency, but the detailed information on that is years old. Our needs are fairly simple: 2 servers, a shared array, and I'm reasonably sure that we don't use locking. However we'd like failover to work reliably without loss of data.

View 1 Replies View RelatedI have a drive that I am going to use for media storage, but i am not sure which filesystem type to choose. It was originally ext2 since it had Fedora on it once before, but I want something that is accessible (ie read/write) from a Windows system. I think as long as I share the mount via Samba or something I should not need to worry about the type of system it is.Before thinking, I chose fat32 until I remember the limitations. Since this drive will be mounted by Fedora, I believe I should stick with ext*, but I'm not sure which to choose.
