search for: 10tb

Greetings. I am trying to create a 10TB (approx) ext3 filesystem. I am able to successfully create the partition using parted, but when I try to use mkfs.ext3, I get an error stating there is an 8TB limit for ext3 filesystems. I looked at the specs for 5 on the "upstream" vendor's website, and they indicate that the...

Hi, How can we horizontally scale Dovecot across multiple servers? Do we require to install independent instances of Dovecot on each server? We are planning to use a NAS/SAN device using ZFS or EFS for email storage. Each logical unit will be of 10TB and similarly as the no: of user increases we are planning to add multiple 10TB units. In this case how we can manage the email storage on multiple volumes from Dovecot. The configuration of our existing system is:- Dovecot 1.0.15 / Maildirs Postfix 2.5.5 Debian 5.0.9 (Lenny) MySQL 5.0....

I am trying to use a large (10TB) reiserfs filesystem as an rsync target. The filesystem is on top of lvm2 (pretty sure this doesn't matter, but just in case.) I get the following error when trying to sync a modest set of files to that 10TB target (just syncing /etc for now): rsync: writefd_unbuffered failed to write 4...

Okay, I must be a total Nerf-herder, but I am trying to find info as to how big a volume samba can actually share - eg if I have a 10TB volume, can I share it via SMB (assuming everything else is ok)? Specifically for samba 3.0.10... No matter what and where I search I can't find a damn thing! Can anyone here shed some light? Thanks, Daniel.

...timeout=2,acl,_netdev 0 0 where holyscratch is a RRDNS entry for all the IPoIB interfaces for fetching the volfile (something it seems, just like peering, MUST be tcp? ) but, again, when running just dumb,dumb,dumb tests (160 threads of dd over 8 nodes w/ each thread writing 64GB, so a 10TB throughput test), I'm seeing all the traffic on the IPoIB interface for both RDMA and TCP transports...when i really shouldn't be seeing ANY tcp traffic, aside from volfile fetches/management on the IPoIB interface when using RDMA as a transport...right? As a result, from early tests (the b...

It should be, since the bricks are smaller. But given you're using a replica 3 I don't understand why you're also using RAID1: for each 10T of user-facing capacity you're keeping 60TB of d...

Hello, I?m currently using another open source search engine/indexer and am having performance issues, which brought me to learn about Xapian. We have approximately 350 million docs/10TB data that doubles every 3 years. The data mostly consists of Oracle DB records, webpage-ish files (HTML/XML, etc.) and office-type docs (doc, pdf, etc.). There are anywhere from 2 to 4 dozen users on the system at any one time. The indexing server has upwards of 28GB memory, but even then, it get...

...00gb of writes. with rc7 it happens after much less writes, probably 10gb or so, but only on machine 1 for the time being. machine 2 has not crashed yet after 200gb of writes and I am still testing that. machine 1: btrfs on a 6tb sparse file, mounted as loop, on a xfs filesystem that lies on a 10TB md raid5. mount options compress=zlib,compress-force machine 2: btrfs over md raid 5 (4x2TB)=5.5TB filesystem. mount options compress=zlib,compress-force pastebins: machine1: 3.2rc7 http://pastebin.com/u583G7jK 3.2rc6 http://pastebin.com/L12TDaXa machine2: 3.2rc6 http://pastebin.com/khD0wGXx...

Good morning Btrfs list, I have been loading a btrfs file system via a script rsyncing data files from an nfs mounted directory. The script runs well but after several days (moving about 10TB) rsync reports that it is sending the file list but stops moving data because btrfs balks saying too many files open. A simple umount/mount fixes the problem. What am I flushing when I remount that would affect this, and is there a way to do this without a remount. Once again thanks for any...

...ing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering... I''ll get a 10TB test box released for testing OI in a few weeks, but before than, has anyone tested this?

Hello there, as Strahil suggested a separate thread might be better. current state: - servers with 10TB hdds - 2 hdds build up a sw raid1 - each raid1 is a brick - so 5 bricks per server - Volume info (complete below): Volume Name: workdata Type: Distributed-Replicate Number of Bricks: 5 x 3 = 15 Bricks: Brick1: gls1:/gluster/md3/workdata Brick2: gls2:/gluster/md3/workdata Brick3: gls3:/gluster/md3/w...

I''m testing an Iscsi multipath configuration on a T2000 with two disk devices provided by a Netapp filer. Both the T2000 and the Netapp have two ethernet interfaces for Iscsi, going to separate switches on separate private networks. The scsi_vhci devices look like this in `format'': 1. c4t60A98000433469764E4A413571444B63d0 <NETAPP-LUN-0.2-50.00GB>

...t; or checks happen the server load sometimes increases to cause issues. Interesting, we have a similar workload: hundreds of millions of images, small files, and especially on weekends with high traffic the load+iowait is really heavy. Or if a hdd fails, or during a raid check. our hardware: 10x 10TB hdds -> 5x raid1, each raid1 is a brick, replicate 3 setup. About 40TB of data. Well, the bricks are bigger than recommended... Sooner or later we will have to migrate that stuff, and use nvme for that, either 3.5TB or bigger ones. Those should be faster... *fingerscrossed* regards, Hubert

Hello list, I have a ~10TB ocfs2 filesystem in a 8-node cluster. This sits on a logical volume (I know lv is not cluster aware, but I make sure no one touches the lv, while the cluster is running). The LV consists of 5x2TB multipath devices. I recently had errors like this on some nodes: OCFS2: ERROR (device dm-7): ocfs2_c...

...way, the corruption will not affect the other volumes automatically. At the same time, I want to treat these as one unified filesystem, so I effectively concatenate them via aufs. Incidentally, this also allows me to more easily address strange behavior because juggle smaller chunks. If I had 1 10TB fs, and something was going wonky, I would have to have an additional 10TB of capacity to be able to offload it, but as 5 2TB filesystems, I can juggle 2TB at a time. It just so happens that I recently replaced my disk controller and I noticed an unexpected side effect which was not immediately im...

I have a box running snv_134 that had a little boo-boo. The problem first started a couple of weeks ago with some corruption on two filesystems in a 11 disk 10tb raidz2 set. I ran a couple of scrubs that revealed a handful of corrupt files on my 2 de-duplicated zfs filesystems. No biggie. I thought that my problems had something to do with de-duplication in 134, so I went about the process of creating new filesystems and copying over the "good"...

After some extra reading about LVM snapshots & Gluster, I think I can conclude it may be a bad idea to use it on big storage bricks. I understood that the LVM maximum metadata, used to store the snapshots data, is about 16GB. So if I have a brick with a volume arount 10TB (for example), daily snapshots, files changing ~100GB : the LVM snapshot is useless. LVM's snapshots doesn't seems to be a good idea with very big LVM partitions. Did I missed something ? Hard to find clear documentation on the subject. ++ Quentin Le 11/10/2017 ? 09:07, Ric Wheeler...
