Filesystem refresh

Hello again... I've connected my Linux (Mandrake 6.0) box to a huge hardware raid that allows two computers to use the same disk at once, one computer has to be read-only. We have a SUN computer connected to it that has it mounted rw, and the Linux box read-only. I can read the UFS system

I think, that is not the problem, because I had before Slackware and I have md working with full devices and with partitions and it worked properly. Sonia At 08:06 AM 7/29/99 -0400, [EMAIL PROTECTED] wrote: Hi, I have got a problem with md. This is, when I do: mdadd /dev/md0 /dev/hdc

Hi! raidtools is the name for the new versions of the md-tools. RedHat 6.0 with kernel 2.2.5 has raid-driver-0.35 in it??? Please look it up in your kernel messages (#dmesg | grep md). Or do you mean the md-tools to be 0.35. I think Redhat-2.2.5 has raid-0.90 in the kernel and the raidtools 0.90

I don't buy this; the atime updates should be subject to caching, and not get written to the disk more than the update daemon (kflushd or whatever) forces. Jan Edler NEC Research Institute On Thu, Jul 29, 1999 at 09:20:15AM -0500, Tim Walberg wrote: For pure reads, there should be no

Raid5 on logical partitions?

1999-07-29 Thread Bonnie Myers
Apologies in advance for asking such basic questions. Is it possible to use logical partitions on SCSI hard drives to make a RAID-5 array? Can the partion type still be set to 0xfd if its a logical rather than a primary partition? Or will I be better off to construct the RAID array from
