I don't see why this couldn't be a function of the removeable drive

Yes, every modern SCSI controller I've seen uses parity.
But even more importantly--I think it's unlikely that something
like a SCSI controller is g
Hi
I know what "swapoff -a" will do if there is data laying on the
swap-partition; but the intention should be to have _NO_ processes (or
whatever) being swapped out.
At work we got much HP-Workstations and -Servers; everyone got a
swap-partition which is of same size as physical memory (or even
No matter how small the ammount of data in the swap partition, the system

If you have swap, it must be raid if you don't want the machine to fail...
but it's not all that much space...

Hi,
You can run a system without a swap device. But if you do 'swapoff -a'
_after_ a swap device failure, you are dead (if swap had any virtual
data stored in it.)
'swapoff -a' copies virtual data stored in the swap device to physical
memory before closing the device. This is much different than
Hi All,
I have a RAID 5 array with 8 IDE disks. Recently,
it appears that one of the IDE controllers failed
causing its two disks to become unavailable. When
I fixed the controller, the two disks are visible,
but the RAID claims they are out of synch (ie, time
inconsistency --- see below). Have

Hi.
I've set up the raidtools ( RAID5) in my Linux PC and everything seems
to be right.
I am making several tests but I haven't found information about how I
can replace a broken disk.
The steps I am following are:
- Unplug the drive /dev/hdd
- Boot the system. Raid starts in degraded mod
I have some systems using Red Hat 5.2 plus raid0145-19981215-2.0.36
with raidtools-19981214-0.90.tar.gz. On each I have six disks
configured as a single RAID5 device and with an ext2 filesystem with
4K blocksize and -Rstride=16 (since the raid chunk-size is 64).
On running quotacheck (from the qu
