Hi, Thanks the new toolchain uploaded has solve my problem. But now when i m trying to install GlusterHPC i am facing problem. Below are my system specification. Operation SYstem : FC5 64bi [root@localhost gluster]# fdisk -l Disk /dev/sda: 82.3 GB, 82348277760 bytes 255 heads, 63 sectors/track, 10011 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 10011 80308935 8e Linux LVM [root@localhost gluster]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 73G 14G 55G 20% / /dev/sda1 99M 12M 82M 13% /boot tmpfs 501M 0 501M 0% /dev/shm I working fine upto the stage of Active Nodes and than it`s starting Extensions to transfer to client sytem. I am facing the follwoing error on client system. 1) stage3/qutils.gex can`t read stage3/fs-utils.gex can`t read 2)Unable to open /dev/loop read-write (Is a directory /dev/loop has been opened read only.) The device /dev/loop is zero-length and can`t possible store a file system or partition table perhaps you selected wrong device. Actually my partition was unable to mount auto. So i mounted my partition as loop device. B`caz it`s journal file system. On the server end it gives error as : <ip of client> Failed during partitioning. Has anybody tried with FC5 and face such problem than pls. let me know. Thanks
