similar to: ext3 performance with external log

Hi, We are currently doing SpecSFS comparison benchmarking to evaluate advantages of FS journaling to NVRAM card versus journaling to hard disks. We compare NFS performance for Linux file server with ext3 file system in ?data=journal? mode for three different locations of the file system journal: - inside main file system - on a dedicated HD - on an NVRAM PCI card The file system is

Hi everyone, My email server is running CentOS 3 and I can't upgrade it to CentOS 4 using the CD's. At first I thought it was the old Megaraid card (that's no longer supported), so I replaced that with a new card. I've tried ISO's from CentOS 4, 4.1 and now 4.2 which I've tested and booted in other machines. Just not this one. I've never had a problem like this

I want to buy a Lenovo U160 laptop, Core-i7, 16gb DDR3, 500gb HD What I am trying to accomplish is to use a Hypervisor that boots up and then have a Windows, Linus and OS X VM that also gets started up and I can interact between them while still on the same laptop. I have a fair number of reasons for wanting this between software development for all of these platforms to pen-testing, etc. Can

(Suggestions for other forums in which to post this question are welcome.) We have CentOS 3.6 x86_64 running on a server with dual 2.2GHz Opterons and a Promise UltraTrak RM8000 connected via an Adaptec SCSI card. We are seeing what seems to be gradual I/O performance degradation over time; it seems to be OK for up to about 90 days, but not long after that both CPUs end up continuously spending

The apology first. If I've offended anyone, or just annoyed anyone, I apologize for that. I sometimes can go 'off the deep end' when I'm being sarcastic (an old habit from my news.admin days when I ran a Usenet site in the early 90's), and I'll try to not go into news.admin mode here in the future. Now, the question. I have a few ideas about how to do this, but am

The latest ext3 patches against linux-2.4.7 and linux-2.4.7-ac3 are at http://www.uow.edu.au/~andrewm/linux/ext3/ Changes since 0.9.4 include: - Fixed a bug which could trip an assertion failure when using small journals under heavy load in full data journalling mode. - A patch from Ted plus the latest version of e2fsprogs plus the stomping of various ext3 bugs gives us preliminary

I'm setting up a new fileserver. It has two RAID controllers, a PERC 3/DI providing mirrored system disks and a PERC 3/DC providing a 1TB RAID5 volume consisting of eight 144GB U160 drives. This will serve NFS, Samba and sftp clients for about 200 users. The logical drive was created with the following settings: RAID = 5 stripe size = 32kb write policy = wrback read policy =

Hi! I'm working currently on integration of UEFI/SecureBoot support into oVirt. And I have several questions about UEFI/SecureBoot support in libvirt. Can you please help me with them? For UEFI I add the following to the XML: <loader readonly="yes" secure="no" type="pflash"> /usr/share/OVMF/OVMF_CODE.secboot.fd </loader> <nvram

Hi there. I just got a new Adaptec RAID 51645 controller in because the old (other type) was malfunctioning. It is paired with 16 Seagate 15k5 disks, of which two are used with hardware RAID 1 for OpenSolaris snv_98, and the rest is configured as striped mirrors as a zpool. I created a zfs filesystem on this pool with a blocksize of 8K. This server has 64GB of memory and will be running

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, i have a system connected to an external DAS (SCSI) array, using ZFS. the array has an nvram write cache, but it honours SCSI cache flush commands by flushing the nvram to disk. the array has no way to disable this behaviour. a well-known behaviour of ZFS is that it often issues cache flush commands to storage in order to ensure data
