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 -- Ionel GARDAIS System-Network Engineer -------------- next part -------------- A non-text attachment was scrubbed...

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 aux" and an

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. md3 : active raid5 sde1[4] sdd4[3] sdc3[2] sdb2[1] sda1[0] 2930279808 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU] So then I tried the next step: mdadm --grow --raid-devices=5 /dev/md3 But now I have

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 failed array, but keep coming up short. I have a home file server running a RAID 5 array that now will not mount my array. I believe it is telling me there is a problem with the second drive. The basics: RedHat 8.0 kernel 2.4.20-28.8 don't know the

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

a good way of life
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. Another question for our brillants candidates : How to batch the creation of a Samba account ?

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. -- Daniel R.

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,
