Page Conflict - SAN/NAS

Hi,
I want to know whether a page conflict will occur when one thread is reading a read-only database but there are other threads which are "adding" (only) data to the same database and another write-only database - IF I put the data on a SAN/NAS.
I posted this query earlier but have re-scoped the same in the hope to get a meaningful response from this mailing list.
Best regards,
Asif

Hi Asif,
It's a REQUIREMENT that all updating/reading be done from a
single server. Berkeley DB cannot share a cache across multiple
machines, so you can either have a single machine that is
updating/reading, or multiple machines with readonly access.
Even with that configuration, deadlock can happen.
One writer concurrent with readers can cause a deadlock.
In order to resolve a deadlock, an application must use
transactions, as any changes already made before the deadlock happened
(in the thread of control selected to resolve the deadlock), must be
rolled back.

Should FRA be placed in SAN/NAS?

DB Version:10g2 and up
OS: AIX 6.1, Solaris 10
We are configuring RMAN for few of our databases (around 1.5 TB each). Two questions:
1.Should FRA(or non-FRA backup location) be configured in a non-AIX filesystem like SAN/NAS? Is this the standard practice?
2. For DB Storage;which is better , SAN or NAS?

Hi J.Kiechle,
1.Should FRA(or non-FRA backup location) be configured in a non-AIX filesystem like SAN/NAS? Is this the standard practice?It depends on the size of your database and your backup strategy. If it all fits on your internal disks.. why not. But you should also consider long term.
2. For DB Storage;which is better , SAN or NAS?It depends on your storage capacity and performance requirements.

Web-based admin of Linux SAN+NAS

I'm planning on building a SAN+NAS (AoE, NFS, CIFS). I'd like to have web-based tool capable of managing core (eg. AoE, NFS, CIFS) and related (eg. networking, mdraid, lvm, smart) services/functions. I've looked into some of the big names like Webmin, but they seem like too much. I'd also like to actually learn something along the way, but starting from scratch seems daunting. Any suggestions (tools, frameworks, FMs, etc)?

There's always webmin.
https://www.archlinux.org/packages/extra/x86_64/webmin/
It doesn't work too well with BTRFS, but I enjoy it as a way to get a GUI overview of systemd.
Edit: Reading the OP is always a good idea.
If it seems too bloated for you, you can actually remove all the modules you don't need.

Does OVM Manager require access to SAN/NAS VLAN

Hello everyone,
In our setup OVM Manager is installed on its own physical server, using for storage the local disk. Does the storage discovering process requires OVM Manager to have access to the SAN/NAS VLAN, or is this going through the OVM Servers again as it happens during the initial servers' discovering?
Thanks,
Nikos

Hi Nikos,
no, the OVMM doesn't need access to any of the storages the OMV servers are connected to. It is all done through the ovs-agents running on the OVM servers. Those query the hardware and available storage upon the discovery process.
Cheers,

Boot diskless Mac Pro from SAN/NAS/iSCSI

Hi,
is there a way to a boot disk-less Mac Pro from a SAN (or NAS with iSCSI)? For reasons of security and ease of administration, we want to deploy a secure centralized storage that literally hosts the entire company in a single redundant rack. I know Windows and most Unixes can do that and wonder if there is a similar solution for Mac OS X.
Speed is not much a concern (50MB/s is ok). Therefore iSCSI over Gigabit Ethernet should be fine. However, I could not find a bootable iSCSI initiator card for the Mac yet. Is there one?
Any pointers are much appreciated,
Thanks!

There should be no performance penalty at all. A hosted iSCSI drive over Gigabit Ethernet is not slower than a local 3.5" eSATA disk. I checked this with the globalSAN iSCSI initiator in a Mac Pro and an OpenFiler (freeware) server and the drives performed around 70-80 MB/s. Of course, if we were talking about a RAID, a local controller would be much faster, but for single disks this is ok.
The advantage is consolidation, safety and security. All drives of every Mac in an office would be hosted on a highly redundant high-availability server rack (8, 16, or even 32 drives, RAID 6, hot swappable, expandable while running, etc). Nobody would ever notice a drive failure, as it is simply replaced in the rack without downtime.
(1) Adding a new "drive" of any size to any Mac is just a matter of a minute.
(2) Hosted drives behave like a physical local disk. You can partition and format them in any way you like, use hard links (Time Machine?), install other operating systems, anything.
(3) Redundancy and data safety is guaranteed for the entire office.
(4) Backup is centralized and more reliable.
(5) Many iSCSI servers support snapshots: You could return to a previous state of your Mac at any time, as if it was a virtual machine.
(6) If the iSCSI server supports encryption, your data is still safe even if one or more of your Macs (or the server altogether) got stolen.
Usually this kind of setup is run on a fibre channel network in large data centers with hundreds of disk-less server blades and one huge SAN rack full of disk drives. Using iSCSI over cheap ethernet allows small to medium size businesses to benefit from this consolitation technique without spending the $$$ for a FC solution.
I agree that this would certainly not make sense for a single Mac, or two. However, once you have more than, say, five Macs and/or Windows machines, storage consolidation might be very useful.
If it only worked with Macs
Thanks for pointing me to another potential solution. I will carefully check that out. I however can't yet see how it would be possible to have the (read-only) boot image load the iSCSI initiatror drivers and then "redirect" the boot process to a hosted iSCSI disk. The thing is, the OS would have to be installed on a writeable iSCSI disk in order to be maintained, updated, upgraded as usual. All that storage consolidation is pointless, if the hosted drives behave like network shares rather than true local disks.

Libdatrie and man-pages conflict

Doing a system upgrade, I get the following error:
Proceed with installation? [Y/n] y
checking package integrity... done.
cleaning up... done.

/usr/man/man3/index.3.gz exists in both 'libdatrie' and 'man-pages'

What's the best way to deal with this?
Is there a way to find out what depends on libdatrie (I did not install individually)?

Seems to have been fixed -- try again with latest packages.

Pages and Synology NAS

A pages document is saved as a folder on my NAS en cannot be opened on my ipad

Apple changed the file format in the latest versions of the iWork Apps and most 3rd party software is not recogniozing the compressed bundle as a bundle. Instead they see them as folder full of files.
Apple has removed over 90 features from Pages 5.

Can't view frontview home page of netgear NAS, "The URL is not valid and cannot be loaded"

Did a clean install of win XP x64 after a registry problem gone bad. At the same time updated from ff 8.x to the newest 9.0.1 and can at the present not log on to the readynasNV+ from netgear using it's web interface. Also can't view the bitorent page of same machine. On the previous version I got a security pop-up with this but after puting that aside as an exception no further problems with it. I can acces it in IE 6.0 no problem except for similar security pop-ups.

Right, went looking for anything related to 10.0.0135 witch was the adress the working one was on and found that there was an exception in tools, advanced, encryption, certificates, servers tab. Then added an exception for 10.0.0.136 witch resulted in the add exception popup I had in previous versions, one click and it's now working !. Hope this helps anyone experiencing similar trouble for similar equipment.

Two flash elements on page conflict

OK, so I have two differnt flash elements on a new webpage we are working on. One is simply animated flames on a logo, the other is a burning image transition script I just bought.
The page is here: http://www.mediajaw.com/tse
Why do the animated flames stop when the image transition occurs? How do I fix it?
Any help would be most appreciated!

i don't see the flames stopping so you're probably taxing your cpu (or ram but that looks more like a cpu issue).

Waiting page Conflicts with Validator

Hi I introduced a wainting page as discussed in the
days before (http://wiki.apache.org/struts/StrutsPleaseWait?highlight=%28wait%29).
It works excellent but not with the use of validator!
Can someone tell me how to prevent this?
I'm aware that this is a quite tricky problem!
java.lang.NullPointerException

Thanks Starki

Hi,
please send me a testcase to reproduce the issue and I file an enhancement request (ER). Create a zip file and rename ".zip" to ".unzip" before attaching it to a mail. My mail address is in my OTN profile. Alternatively you can file this ER yourself if you have a support contract

Code page conflict

Dear All,
In a non-unicode system (v.46B) I wrote a program to dowload data from a table to a file. However, the file contains weir characters than normal letters and numbers.
My next step will be to upload the file to a unicode system (ECC 6.0), but I am stacked because of this incorrect data representation in the file.
I will appreciate any suggestion.
Thank you in advance and best regards.

NAS/SAN commands to be used in a script

Hi
I have a requirement where in scripts/binaries need to manage the NAS/SAN storage for mirroring or failover issues. Are there any commands for NAS/SAN that can be used as part of scripts or in compiled code?
Regards

Hi Stephen
Thanks for the mail and apologizes for being vague. The below are my requirement details (in brief)
1. Working on solaris 10 OS with Sun StorageTek 5320 NAS/SAN,
2. Do not have any volume manager like Veritas
3. Some of the application directories are defined and stored and mirrored in the SAN/NAS
4. running a real-time system with multiple nodes of which couple of nodes will act as active/standby and the NAS filesystems will be mounted on these.
5. In the event the active fails, standby takes over and continues to read-write the NAS directories as they are mirrored.
6. If the Primary NAS goes kaput, the secondary will take over seamlessly.
What I have is a requirement where in I keep monitoring the health and accessibility of the FS defined in NAS. In the event of a primary NAS failure, I should be able to mount, using commands, the secondary NAS FS seamlessly. That is should umount these and mount those to continue to be able to give unbroken access to the applicaitons. In case the primary NAS is back, need to promote those disks and directories so that they become accessible again for the applications and start mirroring again. To do all this, I need to write a script which will connect to the NAS device is able to run scirpts or such to achieve the above.
Hope I am clear. Else please feel free to shoot back the query here.
Regards

How can I use Pages 4.3 (from Retail pack) template on Pages 5.2 (from Mac App Store)?

This is a new machine running on Mavericks bought last year since my old Mac had a hard-drive failure. Installed Pages (part of iWork '09 package), updated to Pages 5.0 from the Mac App Store and no issues. However, now I need to use some of the old Pages template (San Fancisco Letter to be specific) and the new Pages dosn't have that.
So I had to extract the San Fancisco template from Pages '09 and tried installing under 'My Template' on Pages 5.3. But evertime I'm getting an error while installing. That's when I realised after going through the discussions here, that I can't install a Pages '09 template on Pages 5.3.
So my question is how to use a Pages 4.0 template on Pages 5.3? Is it possible to install Pages 4.3 while Pages 5.2 is still installed? Is there a workaround?
Note: I don't need Pages 4.3 but would like to use some of the templates from there, working on Pages 5.2.
Thanks in advance - Sid

Due to the huge number of missing features in v5.2 that were functional in Pages ’09 v4.3, many of the older version templates expect features/functionality that simply do not exist in v5.2. You should realize that Pages v5 is a brand new application/design, and not a progressive version enhancement to Pages ’09.
When you updated to Pages v5, that process automatically moved Pages ’09 v4.3 into /Applications/iWork '09. You can continue to use the older Pages (and associated custom templates) on Mavericks.
I would resist removing Pages ’09 from your machine, as it is functionally superior to Pages v5.
Templates that you save with Pages ’09 v4.3 are kept in ~/Library/Application Support/iWork/Pages/Templates/My Templates
Templates that you save with Pages v5+ are kept in ~/Library/Containers/com.apple.iWork.Pages/Data/Library/Application Support/User Templates
One of the things that I noticed about the original Pages v5 installation is that it transferred a small subset of My Templates from Pages ’09 into the above User Templates location. These were relative simple templates. The complicated ones did not migrate.
Be certain to make a backup copy of any Pages ’09 template document. Once you open it in Pages v5+, it can no longer be opened in the older Pages application. Providing the template is compatible with Pages v5+, perform a File > Save as Template... to the default location.

Not able to connect to NAS

I have searched and I cannot find anything that helped my situation. I have a NAS that I connect to with smb and it has been working perfectly for the longest time. I updated both of my computers to SL and now my Macbook cannot access the NAS but my iMac can. When trying to access the drive from the MacBook I type in smb://192.168.0.198 and then get the error: "The server "192.168.0.198" may not exist or it is unavailable at this time....". I am also not able to connect to any of the webpages that the NAS hosts using the internal IP address, but again only from my MacBook. From the MacBook if I try and go the the BT page that the NAS hosts I can get to it by the public IP so between being able to access the page that way and my iMac having no problems connecting to anything to do with the NAS I know the problem isn't with the NAS. Also I have not changed anything on my router so I don't see that being the problem. The only thing that has changed is the OS.
I have checked settings and all of the settings on my MacBook match what is on the iMac so I am not sure what else to look for. I have also tried adding port 139 at the end of the ip address and that did not work.
Any help would be appreciated.

he was referring to his own post, not yours. you posted in the right section. can you smb or afp from the macbook to the imac? did you modify your /etc/hosts file in any way? do you have firewall turned on on the macbook? or something like littlesnitch? any of those things could be responsible for this.

Total NAS frustration!

I thought I would be clever and get the only NAS ont he apple store a SMARTDISK one.
I initially got it set up fine.
I then unplugged it from the network and plugged it in using USB as I wanted to transfer my itunes library, it was going to take a day on the network side. This all went fine.
Now plugging it back into the network, the mac cannot connect to it no matter what.
So far I have levelled my router incase that was an issue. I have restarted the mac and I have tried connecting in various ways.
I am able to log into the configuration pages of the NAS through safari with little problem, although for some reason I have to first got my router login page first.
The NAS will on occasion (apparently totally randomly) appear in the network window, but when I click it it says the alias was broken and did I want to fix it?
I have been faffing around with this now for around 3hours and am left wondering precisely what it is Apple Bonjour is supposed to do because this NAS box supports it and its currently active.
Any advice on how I can proceed?
I have tried turning everything off and on again etc etc.

Hi Gary, Did you get sorted ??? I have exactly the same problem - Connected to my PB G4 directly is fine connected to my Netgear hub no sign of the NAS ...going Mad !! Cheers
