Hi all, I've a 30TB hardware based RAID array. Wondering what you all thought of using ext4 over XFS. I've been a big XFS fan for years as I'm an Irix transplant but would like your opinions. This 30TB drive will be an NFS exported asset for my users housing home dirs and other frequently accessed files...

I'd like to mention that test does not allocate 30TB, it allocates 1TB, the rest, ~20TB, is reserved (but not actually used) for ASan shadow memory, it should not be a problem by itself. The test on your bot failed because it tried to reserve 27TB of memory, which is more than set by ulimit earlier in this test. I do not immediately see why it wants...

Hi all, It turns out we lost coverage of the release configuration on the AArch64 buildbots for a while. This is because the machine that we were running the clang-cmake-aarch64-full bot on became unstable (random shutdowns after a day or two of building). Embarrassingly enough, we didn't notice this until now because of a bug in our internal bot monitoring page which listed the

Hello Samba Lists: I am trying to read a 22TB file from a system running OpenSuSE 10.3/x64 (Using whatever version of Samba came out with 10.3/x64). The file is on a 30TB XFS volume. I'm connecting over 10GBit Ethernet from a Windows Server 2003/X64 client. If I try to read the 22TB file, I get the message "Access Denied", but if I try to read 100GB files from the same volume, they read with no problems - please help...Note that I'm not trying to w...

We have a very large zpool containing over 30TB, composed (foolishly) of three concatenated iSCSI SAN devices. There''s no redundancy in this pool at the zfs level. We are actually in the process of migrating this to a x4540 + j4500 setup, but since the x4540 is part of the existing pool, we need to mirror it, then detach it...

Hi all I have this server with some 50TB disk space. It originally had 30TB on WD Greens, was filled quite full, and another storage chassis was added. Now, space problem gone, fine, but what about speed? Three of the VDEVs are quite full, as indicated below. VDEV #3 (the one with the spare active) just spent some 72 hours resilvering a 2TB drive. Now, those green drives s...

Our webserver is configured as such: The actual website files, php, html ,css and so on. Or on a dedicated non-glusterfs ext4 partition. However, the website access Videos and especially image files on a gluster mounted directory. The write performance for our backend gluster storage is not that important. Since it only comes into play when someone uploads a video or image. However, the files

Hi, I wish to establish domain controller based on Centos 5.x.I am considering below setups. 1) Samba PDC 2) OpenLDAP 3) Combination of Samba PDC + LDAP I am confused to select one among above.Can anyone please suggest me?

...sn't support this. How hard would it be to implement this? Is it trivial enough to just change the calls in the code with sed? I think this can significantly reduce CPU usage and increase I/O speed when dealing with fast storage solutions. It can make a huge difference when say transferring 30TB of data. Here are some tests I did. So far the only thing I know of that can use direct I/O is dd which showed a huge improvement. CPU usage went from very high down to under 15% and the speed almost doubled. Is there anything else I can do to tune rsync to give me better speed and/or less CPU...

Hello, I like migrate and consolidate a lot of Windows and samba files servers to a new samba installation. Following situation: ---------------------- At the moment are working about 3000 users in two sites with a amount of 30TB data. Over the next years, it may grow up until 50TB data volume. Planned Hardware: ---------------------- The new disk storage is connected via FC (8GBit/s) to a site redundant SAN. The storage itself uses a online mirror. Planned at the moment is to use 4 servers (two Servers at each site) with...

Are there any best practice recommendations on RAID & disk type for the shared storage resource for a pool? I''m adding shelves to a HP MSA2000 G2, 24 drives total, minus hot spare(s). I can use 600GB SAS drives (15k rpm), 1TB or 2TB Midline SAS drives (7200rpm). I need about 3TB usable for roughly 30 VM guests, 100GB each, web servers so I/O needs are nominal. I''m also

Hi everyone, I am reconsidering how I am using the Puppet nagios functionality, at the moment I am creating one service for each check on each host. A lot of them are identical, and would be better tied to hostgroups to simplify my config. Namely, I have about 5,000 checks in there now which will go up to about 20K over the next month, and it''s taking about 5-10 minutes for a Puppet

Hi Friends, I am currently using Samba on Centos 4.4 as a domain member of AD 2003 with each user having a quota of 2GB(no of users is around 2,000). Now the management wants to increase the quota to 10GB with this there will be more than 20TB of data to be backup weekly which will take lots of hours. Currently Veritas backup software is used to backup data on tapes. There is a concept of

Hi all after being a silent reader for some time and not very successful in getting good performance out of our test set-up, I'm finally getting to the list with questions. Right now, we are operating a web server serving out 4MB files for a distributed computing project. Data is requested from all over the world at a rate of about 650k to 800k downloads a day. Each data file is usually

Hi All. I have a CentOS server: CentOS 5.6 x86_64 2.6.18-238.12.1.el5.centos.plus e4fsprogs-1.41.12-2.el5.x86_64 which has a 11TB ext4 filesystem. I have problems with running fsck on it and would like to change the filesystem because I do not like the possibility of running long fsck on it, it's a production machine. Also I have some problems with running fsck (not enough RAM, problem with

...implementation. I have done a fair amount of reading and perusal of the mailing list archives, but I apologize in advance if I ask anything I should have already found in a FAQ or other repository. Basically, we are looking to provide initially 5 TB of usable storage, potentially scaling up to 25-30TB of usable storage after successful initial deployment. We would have approximately 50,000 user home directories and perhaps 1000 shared group storage directories. Access to this storage would be via NFSv4 for our UNIX infrastructure, and CIFS for those annoying Windows systems you just can''...

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to
