Incredible shrinking volume
by Stephen C. Losen 03 Jan '08

03 Jan '08

I have a fas270 with a volume named "san" containing one qtree and one LUN within the qtree. There is only one aggregate and it contains volumes "san" and "vol0" (root). The san volume is being synchronously snapmirrored to another fas270. Here are the sizes of everything: df -A Aggregate kbytes used avail capacity aggr0 1253187072 1200347772 52839300 96% aggr0/.snapshot 0 0 0 ---% df Filesystem kbytes used avail capacity Mounted on /vol/vol0/ 16777216 349732 16427484 2% /vol/vol0/ /vol/vol0/.snapshot 4194304 64892 4129412 2% /vol/vol0/.snapshot /vol/san/ 1119669456 1048001824 71667632 94% /vol/san/ /vol/san/.snapshot 58929968 102176 58827792 0% /vol/san/.snapshot lun show /vol/san/vmail/lun0 900.1g (966503301120) (r/w, online, mapped) I got an autosupport email saying that the san volume had run out of space, and it was indeed 100% full. I grew the san volume a little bit and I also reduced the snap reserve to 5%. Now as I watch the "df" output the san volume continues to slowly consume space. As I understand it, the LUN is a fixed length file, so it cannot be growing. I can only conclude that WAFL metadata files in the volume must be growing, perhaps as a result of the LUN being populated with data, or the snapmirror, or both. I'm concerned that I'll run out of space again in the volume, at which point I am just about out of options for enlarging it. Does anyone know what's going on here? As I have written this email, the space available in "san" has gone from 71667632 down to 71245556 and it's been dropping slowly and steadily for hours. Does anyone know what's going on here? Will I hit bottom before running out of space again? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

R200 aggregate reallocation
by Eino Tuominen 02 Jan '08

02 Jan '08

Hi, I had to add just 2 disk to an existing aggregate. I suspect those disks will end up being a performance bottleneck, so I tried to start reallocation of the aggregate: toaster> reallocate start -A aggr0 Unable to start reallocation scan on 'aggr0': Aggregate created on older version of ONTAP What's the best way to proceed? -- Eino Tuominen

Expand LUN for Exch data
by Kevin Parker 24 Dec '07

24 Dec '07

I'm off network so I can't research this, but want to ensure that I can expand a LUN for Exchange on the fly, no downtime. Plan to use SnapDrive 5.0. Volume is already large enough in capacity.

Hello Toasters one 250gb disk has inserted to 500gb disk aggregate by mistake Is there a way to fix this issue ?

VFM Migration Edition -
by Jacek Nogala 20 Dec '07

20 Dec '07

IHAC who purchased VFM Migration Edition to migrate file services from Windows servers to NetApp filer. And the software seems to be quite complicated. Is there any demo script how to demonstrate to the customer the way it operates (to run live demo on simulator, not flash or powerpoint presentation)? I am looking for complete recipe because due to shortage of time I am not able read all the manuals. Any hints will be also appreciated!

NFSv4/krb5: name<->ID mapping just doesn't work.
by Nathan Patwardhan 18 Dec '07

18 Dec '07

Hello, I'm using an SLES 10.1 client (x86_64) client to mount a NetApp that's running OnTap 7.2.3. My LInux client is bound to Active Directory. My NetApp is bound to my Windows Domain (cifs setup->Option 1, Windows 2000 domain) and 'cifs domaininfo' looks fine to me. NFS was setup to use Kerberos on the NetApp. I'm able to mount my NetApp volume as type nfs4/sec=krb5 and I am able to browse my nfs4 mount. However, by default everybody's permissions are set to nobody:nobody which means that my mapping for users is completely not working. At first, i'd thought that this was strictly an issue with my nfs4 client (i.e. idmapd), but as I look at it more closely, I wonder if I've configured something incorrectly on the NetApp. For example, if I enable a NIS domain on the NetApp, permissions (for both uid:gid) on the nfs4 mount start to work correctly for everybody. Unfortunately, we're trying to end-of-life NIS, so using NIS is not an option. I verified that my nfs.v4.id.domain and domain in imapd.conf are the same. Does anyone have other suggestions for me to consider? Thanks! -- Nate
