search for: qtrees

Good morning, folks. I'm involved in a project to enforce NFSv4 ACL's across a variety of storage platforms, in particular NetApps sharing NFS. That works fiine with the NetApp NFS qtrees, but we'd like to share those with CIFS clients as well. This works, and restricts access the way we expect NFSv4 ACL's to work, but the Windows clients cannot view any of the security settings on the directories or files. Cue the music, and enter Samba 3.5.2. I've reviewed various pub...

Hi, I am looking for a method of syncing NFS directories (Netapp qtrees) that contains NFSv4 ACLs. We copy qtrees (millions of files, xx TB) from one qutree into another one. The only tool we currently use is (netapp internal) ndmpcopy, it preserves ACLs but is slow. Netapp "xcopy" tool is also not aware of NFSv4 ACLs. rsync that is aware of NFSV4 ACLs would...

Good morning! I'm reviewing some corporate storage setups involving NetApps, where the NetApp stores what they call "UNIX Qtrees". So far, so good: those allow the setting of access to the data with NFS4 ACL's, which are fairly sophisticated and allow multiple groups or even multiple users to be granted write access.or read access, besides the normal UNIX group owner. That works fine. But we'd like Windows clie...

Hi, For anyone who is interested; I created some basic scripts based on my current iSCSI block script. http://kinkrsoftware.nl/contrib/xen/block-netapp http://kinkrsoftware.nl/contrib/xen/netapp-lun.py Basically these two scripts allow you to start a vfiler with a qtree of customers. You log in the NetApp upon boot, and can use: netapp://customer1/disk1 It is work in progress... because I

I'm working on some data pipeline issues, and found some interesting results in comparing win2k vs samba. The volume being mounted is a NetApp 960. NetApp provides a way see the # of cifs operations on a given volume/qtree. So I compared how many ops are generated by copying a 12MB file ( a single 2k image ). The initial reasoning behind this testing was seeing if copying a file at the end

I'm newbies in SAMBA and NetApp filer , I use Filer with OpenLDAP as an authentication and authorization server , but look like NetApp doesn't work properly ( can't authentication ) , NetApp engineer suggest me that NetApp work properly with pure ActiveDirectory Environment. not SAMBA + OpenLDAP backend like me have. so I solve this problem by make Samba as native PDC and use

(note: i asked this a few days ago but it *appears* that that post was tossed due to getting excessive bounces from my account. so i'm posting it again, apologies if you're seeing it a second time.) over the next several weeks, i'm teaching some courses in RHEL admin but (unsurprisingly) i'll be using centos 5.5. it's a decently-written, 3rd party course, all the generic,

We are looking for a replacement enterprise file system to handle storage needs for our campus. For the past 10 years, we have been happily using DFS (the distributed file system component of DCE), but unfortunately IBM killed off that product and we have been running without support for over a year now. We have looked at a variety of possible options, none of which have proven fruitful. We are
