Unfortunately, not quite. It still tries to fulfill reservations, which means that if autogrow is enabled it will try to grow (virtual size of) volume. Where it kicks in, when you create FlexClone; it inherits autogrow option and fun starts. It has been discussed recently (lost thread reference), where it apparently could fail snapdrive clone operation. As far as I can tell today there are two safe settings: volume guarantee volume + LUN space reservation enabled volume guarantee none + LUN space reservation disabled Anything in between is bound to have unforeseen side effects. ...

Even if they were reallocated, you can’t please ‘em all. You have a block that is shared by dozen of files. (Logically) adjacent block is shared by dozen different files. You have no way to reallocate them both and keep all files that share these blocks sequentially laid out. So it is not that they are really set in stone – it is more that shuffling de-duplicated blocks around is not going to improve total picture much; de-duplicating one data set will inevitably fragment another. --- With best regards Andrey Borzenkov Senior system engineer Service operations ...

You said “crash consistent”. When host crashes, there is no way to make on-disk content consistent, it is too late.

Your server vendor would be in the best position to provide information about iSCSI boot. This depends on BIOS support, versions of Broadcom firmware, supported drivers etc. It is definitely working. Where it becomes interesting, when you need move the whole server to different system. There are solutions that offer automatic failover in case of server failure (including making proper LUN masking adjustments etc). The nice thing is, no changes are required in operating system or application, no cluster software. Windows 2003 cannot be installed directly on iSCSI initiator; you need to install it on local disk, copy onto iSCSI LUN and make adjustments so that system boots. Some vendor installation tools automate it. Windows 2008 can be installed directly on iSCSI LUN; again it is best to ask server vendor about required driver versions, BIOS support etc. ... View more

For example, if I have a 100MB LUN and grow it to 100GB, the LUN geometry will not let you shrink the LUN back down to 100MB again. Why? From my experience in CHS the Heads/Sectors part is fixed during LUN creation; when you resize a LUN, NetApp changes only number of Cylinders. LUN with initial size of 100M would have CHS=13/255/63, increasing size to 100GB changes geometry to 13055/255/63. What exactly prevents it goiong back to original 13 cylinders? Actually I just tested it and had no problem going back to 100MB ... View more

As I see it, we're talking about looking at every unix client and application, understanding what user needs to access what NFS data, I am not sure I quite understand it. Every file on NFS share has well defined permissions which do not depend on who is accessing this file. These permissions can be fetched and converted alongside with copying file itself. It is relatively straightforward to generate Windows ACLs from Unix mode bits once user mapping issue is resolved. The files you downloaded are from internal usermapper service. Every user on Celerra must have Unix UID and GID. For CIFS users mapping can either be configured manually, or as a last resort usermapper generates them automatically. So this database likely contains random UID for every Windows user ever accessing your Celerra; but it does not contain anything directly related to file permissions. It could be useful to find out which Windows user owns file in case file owner comes from CIFS side. ... View more

I confirm that after disabling UAC it works. By default W2k8 comes with local policies Admin approval for Built-In Administrator = disabled and Run all administrators in Admin Approval = enabled, which explains why it did work for domain admin (I was on domain controller where domain admin == local admin). Changing Behaviour of elevation prompt for administrators to Elevate without prompting does not fix it. In plain words it means that RBAC with SDW CLI is impossible with UAC enabled. Not nice ... ...

What an interesting example of bad interaction of different features I guess NetApp will have to eventually provide explicit autosize control during FlexClone creation just like the one for volume guarantees. Now my question - does it actually make clone connect to fail or is it just cosmetic issue? Because testing it (without SD involved) I can reproduce this behaviour, but clone is created, I can online LUN and clone actually does not consume any space in aggregate (even though it seems to): Mon May 10 18:09:46 MSD [wafl.vol.autoSize.fail:info]: Unable to grow volume 'test1_clone1' to recover space: Volume cannot be grown beyond maximum growth limit simsim*> lun show         /vol/test1/lun1               70m (73400320)      (r/w, online)         /vol/test1_clone1/lun1        70m (73400320)      (r/w, online) simsim*> df -r Filesystem              kbytes       used      avail   reserved  Mounted on /vol/test1/             102400      72028      30372          0  /vol/test1/ /vol/test1/.snapshot          0         40          0          0  /vol/test1/.snapshot /vol/test1_clone1/      122880     122880          0    (71832) /vol/test1_clone1/ /vol/test1_clone1/.snapshot          0         52          0          0  /vol/test1_clone1/.snapshot simsim*> aggr show_space aggr0 Aggregate 'aggr0'     Total space    WAFL reserve    Snap reserve    Usable space       BSR NVLOG           A-SIS       1024000KB        102400KB         46080KB        875520KB             0KB             0KB Space allocated to volumes in the aggregate Volume                          Allocated            Used       Guarantee test1                            103156KB         72492KB          volume test1_clone1                       1236KB           408KB            none Also notice, that this issue happens only if you create non-space reserved clone.

Where did the 400GB go? They have been reserved by virtue of fractional_reserve being set to 100. In my example above you see that it tries to reserve 70M contained in base snapshot. It fails to do it, but because clone space guarantee is "none", NetApp ignores this error and let me continue. ... View more
