Locking of Files and server clusters
by Morgan, Joshua 25 May '01

25 May '01

Here is the Scenario: We have SQL7 Server running with its Databases on an F760 We are using Legato Clustering Software If the main SQL Server dies and the cluster software tries to bring up the backup server, we get a message saying that the Database files are still locked by the downed server. Does anyone know of a way to script unlocking the files? We can manually do it through server manager but that is no good for Disater Recovery.

Yep, set the ignore_acl option and it works great! Thanks guys.

RE: Why is root not root?

This is explained in the security troubleshooter. "I'm root but I can't do everything I want to on the filer" http://now.netapp.com/NOW/knowledge/docs/olio/guides/53_troubleshooting/faq… By default, NT security does not allow administrators to access data unless it is granted in the ACL. However, NT administrators can take ownership and grant themselves access. Not all shops want this behavior. In particular, if you have a Unix-centric administration model you can have "root" override NT-style security by turning on the "cifs.nfs_root_ignore_acl" option. That option is available in 5.3.7 and later versions of ONTAP.

DS14 experiences?
by Moshe Linzer 25 May '01

25 May '01

Is anybody using the new DS14 disk shelves? Are the shelves and drives reliable? My FC9's and 36GB drives have been rock solid for the past year or more, and I am leery of jumping into new technology. But getting twice the capacity in the same footprint is just too enticing! Moshe

RE: recovering data from user's snapshot directory?
by Muhlestein, Mark 24 May '01

24 May '01

You can use "scopy.exe" from the NT resource kit to get this data, since it uses backup-mode access which bypasses the security on the files. Mark -----Original Message----- From: brad(a)ThoughtWorks.com [mailto:brad@ThoughtWorks.com] Sent: Tuesday, May 22, 2001 2:23 PM To: toasters(a)mathworks.com Subject: recovering data from user's snapshot directory? We have a few employees that have left the company and I need to get their data back from their snapshot directories (the original files and folders were deleted as well as the usernames). The volume is a CIFS homedrive setup and if I try to take ownership of the folders under the snapshot directory, I cannot. I also cannot give myself read access to the folder. Has anyone else has this problem? I'm logging in via the administrator account and it still does not work. Thanks in advance for your help.

Ah yes, I remember using this one. Nice memory, Graham! Hopefully that's the right answer for you, Chuck. Let us know!

Probably because the file has an NT ACL that has been set so tightly that the root user cannot access it without taking ownership first, which cannot be done very easily from the command line. Setting this (hidden) option will make this type of problem a thing of the past: options cifs.nfs_root_ignore_acl on I used this extensively at my last position with very good results.

That's the problem, even with root == Administrator I still run into directories(folders) that I cannot access (as root). I don't have a problem with the flexibility, I just want to be able to manage my data from one machine, my admin host.
