CentOS 7 - Have 2 disks, each with a biosboot partition, can only boot off one of them
Hi all,
I used a kickstart script to setup a new machine of mine with RAID 1
(I couldn't get anaconda to create matching partition schemes). So I've
now got /dev/sdg1 and /dev/sdh1 as 'bios_grub' (/dev/sd{a-f} are a
separate array).

USB disk dropping out under light load
Hi all,
I'm running a pretty updated CentOS4 x86_64 server (Still on kernel
2.6.9-42.0.2, but appart from that fully up to date against the official
repos) with a USB-disk attached (the USB-disk is a 750G Seagate disk in a
Seagate enclosure) over a USB hub.
I've noticed several times that after longish periods of activity, the disk
drops out (log from last time, below). In this case,

LVM and hotswap (USB/iSCSI) devices?
Hi list,
I'm having one of those 'I'm stupid' -problems with LVM on CentOS 5.2.
I've been working with traditional partitions until now, but I've
finally been sold on the theoretical benefits of using LVM, but for now
I only have a huge pile of broken filesystems to show for my efforts.
My scenario;
I attach a disk, either over USB or iSCSI.
I create a PV on this

Locally attached disk is seen, 40 gig PATA in USB enclosure is not.
Hi Folks,
When I boot ISOLinux, the locally attached disk is visible but the PATA
40 Gig in a USB attached enclosure is not. The locally attached disk
has no bearing on what I am doing and to avoid confusion will not be
mentioned again. Everything is happening on the 40 Gig.
Let me explain.
The goal is: Copy an installation iso to the disk, boot the disk and
install it on that disk. I have

Multi-Card reader (SD, MMC, etc) and CONFIG_SCSI_MULTI_LUN kernel option in 34.0.2. Workaround
Hi folks,
Im trying to get a multi-card reader on centos (SD, MMC, and so, 4 card
slots) and i have read (http://www.cs.sfu.ca/~ggbaker/personal/cf-linux)
that CONFIG_SCSI_MULTI_LUN should be enabled on kernel (=Y) but current
34.0.2 doesn't have it enabled by default, is there any particular
reason to not be enabled?
By the other hand i've also tweak the /etc/grub.conf file to boot the

Bootable 5.4 USB key...
Hi,
I tried to convert my working 5.3 USB bootable key to 5.4 and I apparently cannot get syslinux to find/read its configuration file anymore...
I followed the same process as before:

syslinux -s /dev/sdg1
cd /media/BOOT
cp -rv /mnt/cdrom/isolinux syslinux
mv syslinux/isolinux.cfg syslinux/syslinux.cfg

How can I get the mapper device permissions set on reboot?
When I attempted to try this...
# cat /etc/udev/permissions.d/50-udev.permissions | grep mapper

But it did not seem to work...

question about replacing a drive in raid10
Hi all,
I have a question about replacing a drive in raid10 (and linux kernel 3.8.4).
A bad disk was physical removed from the server. After this a new disk
was added with "btrfs device add /dev/sdg /btrfs" to the raid10 btrfs
FS.
After this the server was rebooted and I mounted the filesystem in
degraded mode. It seems that a previous started balance continued.
At this point I want to
