Disaster recovery using cvfsb ( spaces issues )

Hi All

Have a customer with an Xsan volume that got nasty, it won't mount anymore

We can retrieve files using the method described in this page

http://www.xsanity.com/article.php/20080327101938881

running commands like this works fine

[code]echo “save 0x3c4de8 /Volumes/restore/Projects/moonshine” | cvfsdb Testvol/code

My main issue is with folder paths that's got spaces in it ( tell me about naming guidelines ! )

If the destination has a space in the folder name, it doesn't work

So if we have a directory structure like VolumeRoot/Face/To Sound/

I can't retrieve files to it

running this

[code]echo "save 0x357c51f /Volumes/Restore1/Face/To\ Sound/test2.dv" | cvfsdb XSAN/code

gives : [code]syntax error. Enter "help" or "?" for help/code.

While if I eliminate the space, it works fine like below

[code]echo "save 0x357c51f /Volumes/Restore1/Face/To-Sound/test2.dv" | cvfsdb XSAN/code

I've tried various options for the syntax, but none seems to work with the spaces

Needless to say the volume structure is full of spaces ( as well as & , / and non-latin characters too! ) , so it's close to impossible to rename all such folders

Any help about including non-latin characters in this command syntax would be appreciated

Regards

Volume Can't Be Opened Because You Don't Have Permission

Hi,

We have an Xsan environment, with 2 Mac Mini running 10.8.4 as metadata controllers, Promise x30 RAID, and 5 Mac Pro clients. Today all of a sudden Xsan stopped working. The volume now has a lock on it, and when I double click on it it says:

The folder cannot be opened because you don't have permission to see its contents.

I opened up Xsan Admin, but when I try to set permission

I tried to change permission in Xsan Admin and propagate, but it gave me a strange error saying permission denied. I then noticed that the option to stop or restart volume has grayed out.

If I try to do sudo chown or sudo chmod, it is still permission denied. If I sudo cd into the directory, I can seem to still access the files.

Can someone offer some advice? Thanks.

Xsan Volume will not allow access - RW mount is Locked

Hi All,

I have a client with a Xsan 2.2.2/10.6.8 system where the one Volume has started to act up.

I have run cvfsck -j & -vw and all seems fine.
I'm running snfsdefrag -vr on the volume, and a lot of files are being moved.

The volume will mount on MDC's and clients, but we can not get access to it in Finder.
The volume icon has a Lock on it in XSan Admin and in Finder.
Trying to change Permissions in XAdmin, throw error: 100069 (CANNOT_SET_ACL_FILE_ERR).
I can SU to root and access the volume in Terminal, delete files and such ok.
I have rm -f .DS_Store on the root of the volume, did not help.

I can't se any extended attributes on the volume...

Anyone have a clue what is going on here??

TIA,

How to Patch In to Fiber Switch

Hi,

Supposedly you have 2 fiber switches, and your servers / storage devices all have 2 fiber connectors, do you connect 1 to each switch, or do you connect both to 1 switch and rely on the switch uplink?

Just being curious.

NEED HELP Xsan volume is not mounted (strange problem)

Hi Xsan guru :)
I ask the help in solving the volume mount problem. (advance I am sorry for my english)
All began with the fact that the MDC is rebooted and on the two LUNs were gone XSAN label. I relabeled these LUNs using commands:
[code]
cvlabel -c >label_list/code
then in the file label_list I corrected unknown disks on the label with a same names that were. Then I ran the [i]cvlabel label_list/i command. Finally I got the correct label on all drives.

_Inodelookup invalid inode [0x0]

Hi,

We've just upgraded our Xsan volumes from 10.6.8 Xsan 2.2.2 to 10.8.5.
This went well, apart for one issue.

I needed to reset all the permissions (we went from OD to AD) and while propagating the permissions (and touching all the files) I get about 500 of these errors:

fsm[3962]: Xsan FSS 'XsanVolume[0]': _Inodelookup invalid inode [0x0]
fsm[3962]: Xsan FSS 'XsanVolume[0]': _Inodelookup invalid inode [0x0]
fsm[3962]: Xsan FSS 'XsanVolume[0]': _Inodelookup invalid inode [0x0]

Always the address 0x0.

I've run cvfsck -jv and cvfsck -nv but the check doesn't find anything.

Interesting is that after the restart i've propagated the permissions again and then they are gone. Until the next morning.. I wanted to be sure and run the propagate again, now the error's are back.

Anyone seen these? Google isn't very helpful.

thanks,

Lucas

Xsan 3: Invisible "__defragtmp" files are created after using snfsdefrag (Apple KB)

When defragmenting a file with snfsdefrag on systems running OS X Mountain Lion v10.8.4 and earlier, an invisible "__defragtmp" file may be created which cannot be deleted.
This issue may occur when the following are true:

The defragmented file's name contains precomposed Unicode characters, such as letters with diacritical marks (an accent, grave, or umlaut).
snfsdefrag is run by root.
snfsdefrag is run when the current working directory is on an Xsan volume, or snfsdefrag's recursive option (-r) is used.

XSan Permission Issue and ..

We currently moved from
Mac OSX 10.6.x MDCs using XSAN 2.2.x / Mac OSX Open Directory / XSAN 2.2.x Mac OS X 10.6.x Clients / Promise Storage ( all connected via Fiber Switch )
to
StorNext MDCs ( M440 Appliance ) version 4.7/ New Storage / Old Promise Storage was left intact and still being utilized / New MAC OS X 10.8.x XSAN Clients / Two new Windows 2008 Servers utilizing Stornext Clients All still connected via Fiber Switch.

All The Fiber connected Clients Mac OS X 10.8.x ( XSAN Client ) via Fiber & Two Windows 2008 R2 Server ( Stornext Client ) can see the old ( XSAN ) LUNs & the new ( StorNext ) LUNs and mount the volumes ( lets call this xsan1 and snfs1 ) I can see and access ALL the folders via the MAC OS X 10.8.x fiber clients but via Windows I see the volume but am not able to access "all" the contents. At first I saw the generic permission message indicating " You don't currently have permission to access this folder. Click continue to permanently get access to this folder"
At which point I can choose to continue, and take ownership of the folder. that works to a certain extent but I still get access denied while taking ownership of multiple folders and so on ..... I have been reading up on this issue and came across few things but figured I would come to the PROs and see what is the best way to approach this issue.
I also would like to utilize my Active Directory Domain to authenticate users to login to the MACs and also permission to the old Xsan volume and new snfs volume.
any help is greatly appreciated and I look forward to hearing from the PROs
Thanks

Expected speed? Promise Vtrack E-Class 32TB (16 x 2TB SAS)

What would the expected range of speed be from the following —

Apple Promise VTrack E-Class 32TB RAID Subsystem for MAC OS X w/ 16x 2TB SAS

We would expect to create two RAID6 LUNS and then stripe them together using Mac OS X Software RAID Striping and share the resulting volume using MetaSAN.

I know you guys are more specialising in Xsan rather than MetaSAN, but you are also the most likely group of people to know the answer to this one.

Thanks, in advance.
