[CentOS] nvme fs block size advice
Hi! So, i have nvme which reports the following (lsblk -t): NAME ALIGNMENT MIN-IO OPT-IO PHY-SEC LOG-SEC ROTA SCHED RQ-SIZE RA WSAME nvme0n1 0 131072 131072 3276840960 none 1023 2560B the nvme ns is formated with LBA=1 (4k) option (which is the second option after 512) but both lsblk and parted report sector size logical/physical as 4k/32k The question is : what block size should i use (is optimal) for file-system? Should i try a 32k blocksize? Thanks a lot! Adrian ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

trying with rsync, while the packages are downloaded but the repodata is
not and is actually impossible to be used by clients. while i try to
recreate the repodata with
createrepo -C -d --workers=4 ${repo}
where ${repo} is the sync destination where it contains
%arch/{Packages,repodata} directories
the clients throw errors like:

For the internal variety in a standard rack-mount server you'll usually see either 2 or 4 iPass cables (each of which support 4 drives) connected to the backplane. The marketing material you've referenced has a white lie in it: supporting more than 16 drives on a single card is very likely only possible with an additional SAS expander board. I believe Supermicro does sell some pre-configured systems with ok, then i should give a little detail : the purpose was to have an 1U server as a head of a JBOD chassis that have 2 SAS backplanes.

I'm sure he's referring to what is essentially lane sharing. A SAS expander in many ways is like an ethernet switch. You have 8 lanes coming off your SAS3008, 4 each in the SFF8087 connector or 8 individual SATA like sockets on the motherboard. You can plug any number of these into a host port on a SAS expander and you then have n*6Gbit of bandwidth to the expander from the host. Then you plug targets and/or additional expanders into the downstream ports. Everything on the downstream ports has to share the bandwidth so you can run into a wall if you try to push to much bandwidth to to many devices at once. In practice though it is not usually a problem with a 2-3x over-subscription of lanes with HDD's. You will see it though if you are really pushing allot of SSD's. yeah, but i am not (6 gbps for 24 hdds is ok for me) .. so i would to get back to my original problem/question : why would the mb integrated lsi 3008 not support sas cascaded (through sas backplanes) more than 8/16 devices (as the OEM technical support said) when 3008 specifications says that it could? Did anyone tried to use sas cascaded storage with some integrated in the motherboard sas chip?

The package in question is from a particular science-related repo and i i got an answer that the package is that way because there are potential users that use i686 software (in the context that that software is only supported for x86_64 distros..) So: are there any best-practices rules that say :do not mix arch in packages, better split them ? Thanks!

uninstall and would clean up the packages?

a linux system never needs to be re-installed

i already did this (for el6 - see below) .. i have the rpms, but at this
moment would be for me too time consuming to learn how to make a repo. i
imagined that for professionals (that did this thousands of times) would
take very little time to rebuild the rpms and put in their repo (repo
that is installed on all my machines)
updating it yourself. It's sometimes as simple as grabbing the new src tar
ball, incrementing the build number and running rpmbuild -ba blah.spec.
Sometimes there are patches to merge or library issues, but I've had really
good luck at that. Also, if you show up to an interview and say you build
well, on el5 doing the exactly the same things like on el6 there are
some files that are not found (this is for rrd) .. so i was hopping to
have at least some guidance.. (another bad thing is that i dont have a
virtual machine for building and i tried this on an old production
server (as an dedicated user))
In the end (when the importance of time for doing this will be greater
than my current job activities) i will follow this info:

your own rpms for consistent builds and deployments you're going to get a
lot farther than most people.
If you get stuck look at

They require much more than before, it may be due to the switch from 32 to 64 bits, but to me this cannot explain the whole difference. it would seem that there is a malloc(glibc) behaviour ... i seen in other list an advice to use : export MALLOC_ARENA_MAX=1 export MALLOC_MMAP_THRESHOLD=131072 in order to decrease the used memory .. HTH, Adrian Here are our investigations. We used the following simple benchmark: 1. Run a python script and check the memory that it requires (field VIRT of the top command). This script is: import time time.sleep(30) print(done) 2. Similarly, run and check the memory of a simple bash script: #!/bin/bash sleep 30 echo done 3. Open a R session and check the memory used I asked 10 of our users to run these three things on their personal PCs. They are running different distributions (mainly ubuntu, slackware), half of them use a 32 bits system, the other half a 64 one. Here is a summary of the results: Bash script: Avg Min Max 32 bits 54004192 9024 64 bits 12900 1 16528 Python script: Avg Min Max 32 bits8500 5004 11132 64 bits32800 3 36336 R: Avg Min Max 32 bits26900 21000 33452 64 bits100200 93008 97496 (as a side remark, the difference between 32 and 64 is surprisingly big to me...).

The default is 1.2 for --create, and to guess for other operations. The default can be overridden by setting the metadata value for the CREATE keyword in mdadm.conf. Options are: 0, 0.90 Use the original 0.90 format superblock. This format limits arrays to 28 component devices and limits component devices of levels 1 and greater to 2 terabytes. It is also possible for there to be confusion about whether the superblock applies to a whole device or just the last partition, if that partition starts on a 64K boundary. 1, 1.0, 1.1, 1.2 default Use the new version-1 format superblock. This has fewer restrictions. It can easily be moved between hosts with different endian-ness, and a recovery operation can be checkpointed and restarted. The different sub-versions store the superblock at different locations on the device, either at the end (for 1.0), at the start (for 1.1) or 4K from the start (for 1.2). 1 is equivalent to 1.2. default is equivalent to 1.2. given the existence of 2+ tb hdd, metadata 0.9 is no go from the start ... so, why 0.9 ?

[CentOS] OFFTOPIC :: IB hardware choice
Hi! I would need an advice from those that use IB (as admins :) ) i have a choice between : 1. Mellanox InfiniHost® III Lx HCA card, single-port CX4, DDR, PCIe x8, mem-free, tall bracket, RoHS R5 2. QLogic Single Port 20 Gb InfiniBand to x16 PCI Express Adapter (Single Pack) aside the price is there anything else that could help me make a discrimination between this two? (these will be used in twin servers for a small (up to 24 nodes) parallel cluster) Thanks!

It seems that everything is ok :) Thanks a lot! Adrian Brilliant! Thanks for reporting back. If you have no issues with it, I'll move it My pleasure :) from testing to the main repository in a few days and will maintain it beside using it, is there other things to do for testing if everything is alright? from there, so if you have elrepo installed, a 'yum update' will find future package updates for you. great! thanks! BTW, because it's a kABI-tracking kmod package, it will work seamlessly across kernel updates :-) thats great :) Thanks!

[CentOS] fs for 16 TiB partition
Hi, What would you recommend as an FS for an partition greater than 16 TiB? This is for an production server (that is, no ext4 recommendations please :) ) What experiences did you had with your preferred FS ? (good and not so good points) Thank you, Adrian smime.p7s Description: S/MIME Cryptographic Signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

(good and not so good points) Thank you, Adrian Does anybody actually run such a thing on Linux? We will .. 2 X RAID6 each with 12 drives (24 drives machine) with 2 TB drives .. that is 20 TBs each volume How long does a FSCK take once it's 80% populated? i strongly hope that i will never know :)) it have 2 redundant PSU each on different ups ... How much RAM does that need? minimal .. is an storage only machine so 4 GB is enough as the connection is only GigE The FSCK on my Virtuozzo-partition takes long enough - and it's only 500 GB or so. Even for home its efficient to have an ups for each machine..
