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 & Regard...

...s, 2x JetStor and a Dell MD3000. The Coraid and JetStor are network connected via ATA over Ethernet & iSCSI. The disks are also being upgraded to 1TB in the process. I do plan to use unify to bring most if not all the storage together. My first question is that since these units are over 12TB after being RAIDed, should I divide them up into smaller bricks or just use the entire 12TB+ as one brick? What other things should I consider? Thanks for the help! -- Matt

Hello, I have several ~12TB storage servers using Solaris with ZFS. Two of them have recently developed performance issues where the majority of time in an spa_sync() will be spent in the space_map_*() functions. During this time, "zpool iostat" will show 0 writes to disk, while it does hundreds or thousands of sm...

I created a zfs pool with dedup with the following settings: zpool create data c8t1d0 zfs create data/shared zfs set dedup=on data/shared The thing I was wondering about was it seems like ZFS only dedup at the file level and not the block. When I make multiple copies of a file to the store I see an increase in the deup ratio, but when I copy similar files the ratio stays at 1.00x. -- This

Hi All, I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection? So if I have 8 x 1.5tb drives, wouldn''t I: - mirror drive 1 and 5 - mirror drive 2 and 6 - mirror drive 3 and 7 - mirror drive 4 and 8 Then stripe 1,2,3,4 Then stripe 5,6,7,8 How does one do this with ZFS?

I have done it numerous times.

Can anyone provide a tutorial or advice on how to configure a software RAID 5 from the command-line (since I did not install Gnome)? I have 8 x 1.5tb Drives. -Jason

...sers 145M 113M 33M 78% /usr/local/atmail/users very little of this is compressed (zlib plugin enabled during christmas). I'm surprised that the destination server is so large, was expecting zlib and mdbox and SIS would compress it down to much less than what we're seeing (12TB -> 5TB): $ df -h /srv/mailbackup Filesystem Size Used Avail Use% Mounted on /dev/mapper/mailbackupvg-mailbackuplv 5.7T 4.8T 882G 85% /srv/mailbackup Lots and lots of the attachement storage is duplicated into identical files, instead of hard linked.

Hey, I installed 2 new data servers with a big (12TB) RAID6 mdraid. I formated the whole arrays with bad blocks checks. One server is moderately used (nfs on one md), while the other not. One week later, after the raid-check from cron, I get on both servers a few block_mismatch... 1976162368 on the used one and a tiny bit less on the other...?...

Hello all. Our Gluster 9.6 cluster is showing increasing problems. Currently it's composed of 3 servers (2x Intel Xeon 4210 [20 cores dual thread, total 40 threads], 192GB RAM, 30x HGST HUH721212AL5200 [12TB]), configured in replica 3 arbiter 1. Using Debian packages from Gluster 9.x latest repository. Seems 192G RAM are not enough to handle 30 data bricks + 15 arbiters and I often had to reload glusterfsd because glusterfs processed got killed for OOM. On top of that, performance have been quite...

I want to upgrade our storage system to Gluster V3.3 and upgrade hard drives to 4TB models. I purchased a new server (same base hardware as the existing ones), but outfitted with new controller (that supports 4TB drives) and with 8 x 4...

Hey folks, I did some googling on this but did not come up with much. I'm using rsnapshot which uses rsync, and I notice some pretty long pauses in the xfers as you can see on this graph from "munin". THe machine in question right at the moment is doing nothing but rsyncing ( rsnapshoting ) some 12T of NAS storage to local disk, so there is nothing else going on at all.

...entries that are not healing after a couple months of (not really heavy) use, directories that can't be removed because not all files have been deleted from all the bricks and files or directories that become inaccessible with no apparent reason. Given that I currently have 3 nodes with 30 12TB disks each in replica 3 arbiter 1 it's become a major showstopper: can't stop production, backup everything and restart from scratch every 3-4 months. And there are no tools helping, just log digging :( Even at version 9.6 seems it's not really "production ready"... More l...

...pany as this is required for some other projects. But we want to keep our nice 5+ samba-server providing fast 50TB+ of storage. So we have to find a way to nicely integrate the storage with the new ADS installed. Therefor I installed a Testlab consisting of 2 debian etch storage-servers with each 12TB lvm-based storage attached. Also we have 2 MS 2008 Server SP1 as PDC and BDC. Further we have some Windows XP 32 and 64 Bit clients as workstations for testing. Now we setup everything and decided to use samba 3.2.0 as there are some bugs related to W2k8 server are solved. So I build debian packag...

I'm trying to improve the setup of our Dovecot/Exim mail servers to handle the increasingly huge accounts (everybody thinks it's like infinitely growing storage like gmail and stores everything forever in their email accounts) by changing from Maildir to mdbox, and to take advantage of offloading older emails to alternative networked storage nodes. The question now is whether having a

...es to storage servers (all with 3ware cards offering RAID5 arrays) that collectively serve 10TB of images. The data grows by 2TB every year. This has been working so far but this current implementation is facing growing pains so I'm looking at more scalable options. Something that will offer 12TB of storage and room to grow by adding more storage as needed. Currently the Apple Xserve RAID 7TB offerings connected to a QLogic SANbox 5200 fibre switch looks very appealing. Especially considering the Xserve RAIDs are listed in Red Hat's RHEL HCL and Google searches have revealed successfu...

...the folliwing ok for a small cluster that will serve hundreds of virtual machines? - two DELL R515 with 12 2TB (or 3TB) SATA disks - RAID 1 between every 2 disks on each server - one brick for every RAID1 - distributed replicated clusterd between bricks. This should give me a big cluster made of 12TB Is a raid10 better then many distributed bricks? With bricks should I have more flexibility in case of disk expansion -------------- next part -------------- An HTML attachment was scrubbed...
