anaconda, kickstart, lvm over raid, logvol --grow, centos7 mystery
I am testing some kickstarts on ESXi virtual machine with pair of 16GB disks.
Partitioning is lvm over raid.
If i am using "logvol --grow i get "ValueError: not enough free space in volume group"
Only workaround i can find is to add --maxsize=XXX where XXX is at least 640MB less than available.
(10 extents or 320Mb per created logical volume)

can not lvcreate after lvm snapshot and "xm mem-set" and lvremove
I am not sure if it''s a xen bug or lvm bug, or just my bad hardware,
but here''s how to reproduce:
/dev/vg0/centos1 is lvm block used by a domainU, it''s 8G in size.
#lvcreate -L8192M -s -n snap1 vg0
#mount /dev/vg0/snap1 /mnt
do some copying files here

not removed! it says can''t allocated memory

File System Size Limits?
-----BEGIN PGP SIGNED MESSAGE-----

Is there some limit on the size of a file system which can
be shared via samba? I'm trying to set up a file server
with a 100GB shared partition and it doesn't want to work.
I'm running Fedora Core 4, and Samba Version 3.0.14a-2.

Installing openSuSE 10.3 as PV-guest on a LVM-drive of a openSuSE 10.3 host
Hi,
how can I install a openSuSE 10.3 PV-guest on a LVM-drive of a openSuSE
10.3 host with Xen 3.10?
On 10.2 with Xen 3.0.3 the openSuSE-YaST-module for managing VMs could
install the system also on block-devices, unfortunately this is not
possible anymore with OSS 10.3 :-(
What I have tried:
- I created two LVM-partitions, one for "/" one for swap.
- Installing an OSS 10.2 PV-guest

lvm errors after replacing drive in raid 10 array
I thought I'd test replacing a failed drive in a 4 drive raid 10 array on
a CentOS 5.2 box before it goes online and before a drive really fails.
I 'mdadm failed, removed', powered off, replaced drive, partitioned with
sfdisk -d /dev/sda | sfdisk /dev/sdb, and finally 'mdadm add'ed'.
Everything seems fine until I try to create a snapshot lv. (Creating a

How to use libguestfs access LVM as non-root user?
Hi,
Following code snippet, running as non-root user, will throw up a
'Permission denied' RuntimeError.
Could someone kindly guide me the correct way to handle LVM disk as
non-root user? Cause as http://libguestfs.org homepage claims, "libguestfs
doesn't need root permissions." A little confused somehow.

[PATCH 1/1] appliance: init: Avoid running degraded md devices
'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present.
This will prevent starting arrays in degraded state.
Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state.
Two new tests are added.
This fixes rhbz1527852.

Ext3 Performance Tuning - the journal
Hello,
I have some performance problems in a file server system. It is used
as Samba and NFS file server. I have some ideas what might cause the
problems, and I want to try step by step. First I have to learn more
about these areas.
First I have some questions about tuning/sizing the ext3 journal.
The most extensive list I found on ext3 performance tuning is
