Transition snapmirror to regular snapmirror
by Basil 23 Mar '16

23 Mar '16

I am trying to migrate a replicated volume to CDOT, but I can't use 7mtt. My plan is to set up a transition snapmirror and do the cutover manually. I can't start the regular snapmirror of the CDOT transition snapmirror target, though. I get "Using a transition volume as a snapmirror source volume is not supported". I have a long outage window, but would prefer to pre-seed the mirror of the new volume. What would you folks suggest?

Moving shelves with root aggr and root vol (7-mode) from one Filer to another
by Martin 22 Mar '16

22 Mar '16

Hi, I have one 7-mode Filer that I will be decommissioning which has data on it I need to migrate to another 7-mode Filer. We don't have space to mirror the data to the new Filer, want to reuse the shelves on the new Filer and this is a quicker cut over. The four DS4243 shelves have a single aggregate (aggr0) with various volumes on it (exported via NFS) including the root volume for the controller (vol0). I found the KB on moving shelves and aggregates between controllers but it doesn't mention what to do about a Filer that has vol0 and root aggr on the shelves. My plan is: 1. Disable disk auto assign on both source and destination Filer on both controllers options disk.auto_assign off 1. Reboot the source controller into maintenance mode 2. Offline aggr0 aggr offline aggr0 3. Uknown the disks on the shelves on the source controller disk assign disk_name -s unowned -f 4. Shutdown the Source Filer and power off along with shelves 4. Power down the destination Filer and add SAS card to new Filer (not enough SAS ports for new loop) 5. Physically moves shelves from source Filer to destination Filer 6. Cable shelves and change shelf IDs along with a powercycle to ensure shelf IDs don't conflict 7. Assign the disks on the new Filer disk assign disk_name 8. As the aggregate is aggr0 and new Filer also has aggr0 it gets renamed to aggr0(1) and foreign 9. Check the status of the new aggregate aggr status aggr_name 10. Rename the new aggregate from aggr0(1) to aggr1 aggr rename aggr0(1) aggr1 11. Online the aggregate on the destination Filer as it is longer labelled as foreign aggregate. aggr online aggr1 12. Check the aggregate status on the destination Filer aggr status aggr1 13. Export the volumes on the destination Filer via /etc/exports and exportfs -r -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Moving-shelves-with-r… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

disk ownership question
by Mark Flint 22 Mar '16

22 Mar '16

Hi list. I have a 3170 running 8.0P1 7-Mode, and am having a problem with auto-assignment of disks. The unit reports that it can’t do auto-assign, because not all of the disks on the loop are owned by the same controller. I was under the impression that software ownership made that unnecessary (you can laugh), but it seems not. KB from 2014 says the same thing. So, question is, has anyone done anything like this (had to reassign a shedload of disks) to make auto-assign work, and could they pass any info on how I can fix this please? Thanks, Mark

7Mode junction-path style on cDOT
by Momonth 18 Mar '16

18 Mar '16

Hi, I wonder if it's possible to employ 7Mode mount point behavior on cDOT NFS SVM? An example: 1. I create a volume "share_01" and by default it shows up as "toaster:/share_01". 2. I'd like to access it as "toaset:/vol/share_01" So, my question is how to add "/vol/" to its junction_path? Cheers, Vladimir

Dealing with a really large number of files in a single directory
by Edward Rolison 17 Mar '16

17 Mar '16

I've got a directory on an NFS server. I think it's been filling up with log files, and may be in excess of a million. (ls -d shows me a 350MB rather than the usual 4k). strace -fTt ls -1 -f is stalling on 'getdents' system call. I assume it'll complete eventually, but ... well, the 'leave it and wait' hasn't yet. Does anyone have any good tricks on a filer for helping me tell that a) this directory is in fact, absurdly large and b) starting to retrieve filenames so I can delete/move them in sensibly sized baches? (I'm wondering if a filer-side ls is going to help or hinder, for example).

missing NFS exports after controller reboot
by Eric Peng 10 Mar '16

10 Mar '16

This is a bit of a quirky issue, wondering if anyone has come across this before? We are hosting a vFiler on a 7-mode array. The other day we had a controller reboot, and it seems after the HA-failover that the NFS exports of the vFiler somehow went "missing" - the /etc/exports file was missing most of the entries. We ended up having to manually recreate the entries, but am wondering if anyone has come across any type of quirky behavior such as this? We are running 8.1.4 P1 on this array, it is hosting many CIFS & NFS shares, as well as VM workloads. We are on 3rd party support now, so cannot open a ticket with IBM Support (rebranded NetApp).
