best parameters for fixed-size files ?
Hi there,
I'll soon run RedHat4 U4 ES with multiple 4TB partitions.
Almost all files on these partitions will have a fixed size of 32MB.
What are the best tweaks around to optimize blocks and inodes ?
Thanks,
Ionel

dealing with mke2fs -T option
Hi,
I have a doubt if I use the mke2fs option the right way.
I formatted two different disks, one with
$ mke2fs -b 4096 -E stride=16 -m 1 -T news /dev/sdd
and the other with
$ mke2fs -b 4096 -E stride=16 -m 1 -T largefile4 /dev/sde
sdd is supposed to get files between 8k and 16k.
sde will handle files with a fixed size of 32Mb.
Then I tried this :
$ dd if=/dev/zero of=/mount-sdx/file bs=4k

owner of a smbd thread
Hi,
I've set up a Samba server accessed by NTWS 4.
When I do a "ps aux" on the server, i can see a line
for each user connected with a "smbd -D" command.
The owners of these commands are mostly root but
sometimes the users themselves.
How to force the owner of the command in order to be
available to get a list of connected users with an "ps

mounting NFS or SMBFS ?
Hi,
I've users connecting to a samba server via WinNTWS
4.0 (home directories are /home/%u)
While workstations have both Windows and Linux
installed, I want to allow users to connect to their
/home directory when logging into Linux.
Do you think it's better to automount the folders
using an NFS mount or to use an SMBFS mount ?
What are advantages and drawbacks of each methods ?

Growing RAID5 on CentOS 4.6
I have 4 disks in a RAID5 array. I want to add a 5th. So I
did
mdadm --add /dev/md3 /dev/sde1
This worked but, as expected, the disk isn't being used in the raid5 array.

Large File Copy to Large ext3 RAID5 Array Often Stalls
I'm experiencing strange behavior from my ext3 RAID5 array and my Fedora Core 2 system. Before I go crazy varying all sorts of tuning parameters, I thought some list subscribers might provide me with useful advice.
The problematic array is:
3x Promise Technology Ultra 100 TX2 PCI cards
6x Maxtor 250GB IDE drives (one drive per cable)
RAID level 5, 128Kb chunk size, EXT3: "mkfs -t ext3

Newbie needs help with failed RAID5 disk
I was hoping someone could either help me or point me in the direction
of a resource. I have searched the web for any howto on repairing a

is telling me there is a problem with the second drive.

Ext3 on RAID5 for video archive server
I am using a terabyte RAID5 with ext3 and created using mdadm, to store jpeg files on a rehdat 7.3 system. I need to write files to the RAID5 at the rate of 800 files per second, and each file is about 10-20 KB in size.
I have tried using data-writeback and the noatime options while mounting, and I am also using a stipe-size of 4MB (since 4MB was the max that mdadm would allow me), and i have

Cygwin, Rsync, and Raid5
Hello all!
I've got CGYWIN running on an NT4 server, which in turn allows me to run Rsync as a daemon on this system. And might I say, it works most excellently, except for one flaw. It doesn't work on my raid drive(s). I have a 56 gig NTFS RAID5 drive running off an adaptec raid-port controller card. I have two other drives in this system, a 4 gig SCSI boot drive, and 60 gig IDE

Thank you all for your answers.
One told me that in order to allow the students to
upload/download from their home directories, FTP or
something like that is a simple and easy choice.
As domain logon and roaming profil is not needed and
FTP can be logged, I'll use this.

Ext3, Raid5, and Quotas on 2.4.14?
I remember that there used to be a problem with disk quotas on Ext3 and
Raid5 on the 2.4.x kernel series. I am running 2.4.14 with Ext3 and
Raid5 and am having problems with quotas and am wondering if I have
something misconfigured or if this combination doesn't work yet.

Raid5 issues
So when I couldn't get the raid10 to work, I decided to do raid5.
Everything installed and looked good. I left it overnight to rebuild
the array, and when I came in this morning, everything was frozen. Upon
reboot, it said that 2 of the 4 devices for the raid5 array failed.
Luckily, I didn't have any data on it, but how do I know that the same
thing won't happen when I have

OT: What's wrong with RAID5
Hi all,
Sorry for the OT.
I've got an IBM N3300-A10 NAS. It runs Data Ontap 7.2.5.1.
The problem is, from the docs it says that it only supports either
RAID-DP or RAID4.
What I want to achieve is Max Storage Capacity, so I change it from
RAID-DP to RAID4, but with RAID4, the maximum disk in a RAID Group
decrease from 14 to 7. In the end, either using RAID-DP or RAID4, the
capacity is the same.

RAID5 suddenly broken
Hello,
I have a RAID5 array on my CentOS 5.6 x86_64 workstation which
"suddenly" failed to work (actually after the system could not resume
from a suspend).
I had recently issues after moving the workstation to another office,
where one of the disks got accidently unplugged. But the RAID was
working and it had reconstructed (as far as I can tell) the data.
After I replugged the disk,

them in another box running CentOS 5 and can see the disks OK.
