Bugs Online behavior/enhancement/bug
by Todd C. Merrill 21 Aug '07

21 Aug '07

So, I've been working with our SE's on trying to pick a new release to which to upgrade. I've also been doing my own research with the Bugs Online part of the NOW site. I either haven't figured out how it works, or the feature doesn't exist. If someone could tell me which one... :) Starting at the Release Comparison Tool: http://now.netapp.com/NOW/cgi-bin/relcmp.on I click on one release and enter another (not on the pre-determined list). I leave "fixes" set (I assume this means "bugs") and choose the checkbox "Filter Bugs to list of watched bugs." Then I click "go." The result I get back is what confuses me. It only shows me 8 bugs. There are 47 bugs on my watch list. What about the other 39 bugs? Do I assume they are fixed in both releases (dangerous!)? Or, was there no state change of that bug in both releases (e.g., it is still *not* fixed in both releases)? It's ambiguous. I really want to know the state of all my watched bugs in both these releases. Feature enhancement request: The ability to get a table of my watched bugs for more than two releases. Bug report (?): After getting the abovementioned list of 8 bugs, if I click the "arrow" icon to sort by severity, it will show me ALL the bugs in those releases (more than 8, more than 47... more like a few hundred), not just the pre-filtered ones (that checkbox is still checked when I click the sort arrow). I would expect it to sort only what is shown. Until next time...

Migration recommendation

We are looking at migrating ~400Gb of data from a PC to a new filer. How can we copy the data efficiently without losing ACL's, etc? -- Sláinte, David Get a safer, faster, better web browser @ http://www.mozilla.org/products/firefox/

Change UNIX security to NTFS - ACLs?
by Roy McMorran 14 Aug '07

14 Aug '07

Hello all, I have a qtree that I wish to change from UNIX security style to NTFS. Experimenting on a test volume I've found that when I make the change the ownerships of all the objects are preserved*, and appropriate ACLs show up for the owners. However, Unix "group" and "other" privileges do not seem to get translated to ACLs. Before I can proceed I really need to find a way to duplicate the group-based permissions that existed on the Unix side. I've started hacking together a script using smbcacls (the ACL utility in Samba). The idea is to set appropriate ACLs for specific groups and "Everyone" based on what the Unix mode bits used to be. Still I wonder if there's an easier way. Has anyone had a similar "challenge"? *In our environment all Unix and Windows user IDs are identical. We use an LDAP back end for Unix authentication and for our Samba-based domain controller. This is 7.2.1.1 on a FAS3020 in case it matters. Thanks for any input. -- Roy McMorran Systems Administrator MDI Biological Laboratory mcmorran(a)mdibl.org

On ONTAP versions 7 that's menu choice 4. How well does this erase the contents? Is it all overwritten? How often? Or is it just a reformat of some kind that only rewrites the meta data? What does 'disk zero spares' actually do? One time, when I really needed to be sure the data was gone forever, I reformatted the disks to 512 bps an ran wipe on them (http://wipe.sourceforge.net/) TIA, -- Bert Kiers XS4All UNIX systeembeheerder, suspected terrorist

I've never understood that logic: If the disk is fully wiped, and "Safe Enough" to consider the data unrecoverable, then why restrict what you can do on that filer. You could always move the disk elsewhere (another filer, or a PC, or whatever) if you really wanted to try to get stuff back from it. Davin.

Increasing the size of disks in an existing array
by Bryano 10 Aug '07

10 Aug '07

Hi, I have 'inherited' several filers including FAS 270's and FAS 940's which only have 72GB drives and we are now running very low on spares and the company I work for is reluctant to buy another shelf, it has therefore it has been proposed that we remove a disk at a time from a volumes raid group and replace it with a larger drive (300GB) and then once the raid has recovered then remove the next disk and repeat the procedure until all the disks in the volumes raid raid group have been replaced with larger ones. My initial question is - is this possible and if so once all the drives in a particular raid group that makes up a volume have been replaced with larger ones will that show immediately as free space available in that volume or will we need to do something else to get the filer to see the additional free space? Thanks -- View this message in context: http://www.nabble.com/Increasing-the-size-of-disks-in-an-existing-array-tf4… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.
