Hi. Is there any ext3 patch for Kernel 2.4.13 out there. I'v been searchin all day for the patch, but can't find any then patch for 2.4.13-ac2 and others. Do they work with 2.4.13? Could anyone please mail me the link if it's avaiable. Thanks. Cheers, :0) best regards, Svavar Orn Reykjavik - Iceland svavar@fiton.is

HI All - I am trying to install the above... The BIOS reports 1 virtual drive, but when C7 is installing there are 0 disks found. >From the hardware it says the raid card is a P420 ... I did a little searching and saw it talking about B320i card - which does not seem to be my card. I'm stuck. Any thoughts? Thanks, Jerry

Greetings, I have a system x3100 m4 system with 64GB SSD for OS and 2x2tb for data as MD device (software RAID). It had Fedora 17 with EFI/ I tried to install centos 6. deleting the existing partitions on the SSD /dev/sdc. sda and sdb are the 2x2tb md device mounted on /home. no joy. googling Questions: 1. Where do I locate the boot loader? /dev/sdc? is MBR (the default with Centos) enough

Hi, I do have one iscsi storage with 4 GBit nics of which currently only one is configured with an ip and which is in productive use by one cent os 6.3 server. Doing some research brought me to the idea to use some nic bonding or multipathing for that storage, but multipathing I did about four or five years ago only once :) Furthormore I can't find the ultimate answer (may be there is not

Hello all. We recently purchased HP Proliant DL380 G7 server and also a HP Lefthand P4500 G2 24TB iSCSI box. The server itself has Quad Ethernet based on the BCM5709 Chipset from Broadcom (NetXtreme II). My main question is about iSCSI offload mechanism, as iSCSI itself is pretty new to me but I have gotten a good hold on it tho. I have managed to setup and configured our Lefthand box into

Hi, I have added 2x2Tb to my existing 2x2Tb raid 1 btrfs filesystem and then ran a balance: # btrfs filesystem show Total devices 4 FS bytes used 1.74TB devid 3 size 1.82TB used 0.00 path /dev/sdd devid 4 size 1.82TB used 0.00 path /dev/sde devid 2 size 1.82TB used 1.75TB path /dev/sdc devid 1 size 1.82TB used 1.75TB path /dev/sdb # btrfs

Preparing to build a small replacement server (initially built in 2005) and normally for the OS I would buy 2x500GB drives and deploy in a RAID 1 configuration. Now we have SSD drives available - does just a single SSD drive offer the same reliability or is there advantage in deploying two in a Raid 1 config? Also, what form factor / interface is best for the SSD OS boot device on a server

Hello Everybody! I set up a fileserver: - Pentium II, 350 Mhz, - 256MB RAM, - Intel Fast Ethernet PCI - VIA-SATA Controller - 2x500GB SATA HDD RAID 1 - Debian 4, Samba 3 - Samba set up in user shares mode without special options, but with the suggested optimizations Clients: - Windows XP Prof SP2 So far it works fine. I can read and write files without problem.

Hi, Given the following R code: library(pryr) data <- array(dim = c(5)) for(x in 1:5) { data[x] <- as.integer(x * 2) } add = address(data) # save address of "data" for(x in 1:5) { data[x] <- as.integer(0) } if (add == address(data)) { print("Address did not change") }

Hey, I'm still waiting for the new file server hardware to arrive so I plan to enable user logins in the meantime without profiles and home directories. Reason for this is quite some pressure from people. The setup on the 2 DCs should be done a day or two. Could there be problems if I configure profiles and home directories some weeks after users logged in for the first time? What if e.g.

Hello all, Is it valid to dereference a pointer that has undef bits in its offset? For example, %p = alloca [8 x i8] %p2 = gep %p, (undef & 8) store 0, %p2 undef & 8 is always less than 8, so technically it will store zero to one of the array's elements. The reason is that I want to improve no-undef analysis by suggesting that a pointer that is passed to load/store is

Hi David, ? Thanks for the correction concerning the "else" issue. ? Taking your code and removing some lines (to increase readability): ? library(pryr) ? data <- array(dim = c(5)) for(x in 1:5) { ?? data[x] <- as.integer(x * 2) } ? #print(data) ? add = address(data) for(x in 1:5) { ?? data[x] <- as.integer(0) } ? if (add == address(data)) { print("Address did not

The match.c code has a loop that initializes an array to -1. I'm considering changing this to a memset() of 0xFF over all the array's bytes, but that depends on a system's representation of a -1 being "all bit on". Should I be anal about this and add a configure check to make sure that we're not running on some weird system where this is not true? Or should I just let
