This is basically done by two methods:– The NTFS kernel module – The NTFS user space programsfrom the kernel source or http://www.linux-ntfs.org/ The NTFS Kernel ModuleHave a check at the wiki page Youmight find an appropriate prebuilt driver for your current kernelversion. Then you can do normal mounts etc on NTFS partitions. Oneproblem here is…
Found and used dvd95 and that works quite nice with gnome – also with kde .. But has problems with some dvds..Testing k9copy. That is exclusively for KDE .. But EL and fedora does it nicely along. Hastested k9copy .. That is nice too .. But did not solve the some-dvdissues .. It seems now…
udev is introduced with the 2.6 kernel (ie not available in RHEL3 and before)And that is solely for device name persistence. It is mainly a problem whendisks are external / via HBA, and the names across reboots and/or clusters mightnot be the same. We have been using devlabel to be able to get some persistence…
Say we have a LVM’ed /dev/sdd1 and we have to mount logical volume LogVol00 in it.. # file -s /dev/sdd1 /dev/sdd1: LVM2 (Linux Logical Volume Manager) , UUID: 7zKduhTHsMa3YD3t2gocYKUDGRP5QvW # vgscan Reading all physical volumes. This may take a while… Found volume group “VolGroup00” using metadata type lvm2 # vgchange -a y VolGroup00 2 logical…

Converting .nrg image to .iso: Fedora:# yum install nrg2iso…$ nrg2iso image.nrg image.iso Note that your .nrg image might already be an ISO (at leas a UDF dump) so you can use it to burn to DVD using GnomeBaker
That is actually a good idea .. it handles switch HA in addition to NIC HA .. And having them on different vlans? .. that is actually somehow mandatory .. you cannot have two switches in a LAN (or VLAN) per its function
Yes .. The nics are slaves to a bond. The bond can be configured to be on more than one vlan with the vconfig command.
active-backup is active/backup .. requires ISL for HA and so on .. but broadcast.. yes .. that sends the packets twice (thrice etc.), eachfor and through every slave.. so theoretically the performance is thesame as if it was on a single link. practically there is some minoroverhead since the HW needs to queue the packet…
