CentOS 8 defaults to XFS, not to ext4, so that row has no bearing on your use case. Although I wouldn’t recommend overriding this default, if you did, I don’t see why you’re worried in the first place. 12 TB < 50 TB, the limit for partitions created by the stock versions of e4fsprogs included with CentOS. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

I also tend to avoid "hardware" raid cards, and prefer HBA cards that present the drives as plain SAS devices, then use the OS's native storage management for raid (mdraid + LVM for Linux, ZFS on FreeBSD, etc).. I generally spec raid 10 for performance data, and raid 6 or 60 for bulk data. raid5 is frowned on these days, disks are so big, and rebuild times are long enough that the risk of a double failure is fairly high. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Hi, We have servers with 500 Tb in line with SAS attachment on a SAN without any problem! It’s perhaps a firmware problem with your SAS card, no? > Le 25 sept. 2020 à 06:25, Amey Abhyankar a écrit : > > Hello, > > I have a blade server with SAS HDD's of 12TB in total. > 3 HDD's of 4TB each. > > Is it possible to install Cent OS 7.8.2003 on 12TB disk space? > I will be installing Cent OS on the bare metal HW. > > I referred = https://wiki.centos.org/About/Product > But slightly confused with the 'maximum file size' row for ext4 FS. > > Thanks & Regards, > Amey. > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos -- Pierre Malard Responsable architectures système GeoSUD IRD - UMR Espace-Dev - UMS CPST Maison de la Télédétection 500 rue Jean-François Breton 34093 Montpellier Cx 5 France |\ _,,,---,,_ /,`.-'`'-. ;-;;,_ |,4- ) )-,_. ,\ ( `'-' '---''(_/--' `-'\_) πr perl -e '$_=q#: 3|\ 5_,3-3,2_: 3/,`.'"'"'`'"'"' 5-. ;-;;,_: |,A- ) )-,_. ,\ ( `'"'"'-'"'"': '"'"'-3'"'"'2(_/--'"'"' `-'"'"'\_): 24πr::#;y#:#\n#;s#(\D)(\d+)#$1x$2#ge;print' - --> Ce message n’engage que son auteur <-- signature.asc Description: Message signed with OpenPGP ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Question regarding cent OS 7.8.2003 compatibility with large SAS disks
what I typically rather do is install the OS on a way smaller drive, that way if the OS drive is trashed, the data array is still there, also, it is easier to create a clean install that way. (of course a partition could work too). On 9/24/20 10:34 PM, Amey Abhyankar wrote: On Fri, 25 Sep 2020 at 09:57, R C wrote: I have done it numerous times. Thanks Digimer & R C for the quick help.

That's not a problem at all. In the server world, 12 TB is actually fairly small. :) -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
