Fstab and preferred options

At one time when I installed my arch systems it was recommended to use defaults,relatime for the mount options for ext4 partitions in fstab. However I am trying to look into an issue with mirror database syncing and I looked through the install wiki areas and did not see any mention of using relatime any more. However I did see in the fstab wiki that noatime was mentioned a number of times.
Can someone clarify what the current recommended mount options are for ext4 filesystems in fstab? (defaults,relatime or defaults,noatime for example)
Thanks

It's all quite a mess (man pages, wiki and reality all show different things), but relatime has been the kernel default for a long while; there is no need to specify it manually. My only fstab option is "discard", and mount outputs:
/dev/sda1 on / type ext4 (rw,relatime,discard,data=ordered)
Also, "defaults" are included by default ( ), so there is no need to specify this option explicitly (i.e. "defaults,noatime" is equivalent to "noatime"). The only situation in which it is needed is when you use no other options — then not writing it would leave a blank space and it would be an error.
So, "recommended options": leave it as it is and only specify what you need.

How can I "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight (and preferably visible, searchable, draggable in Mail App)?

How can I "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight (and preferably visible, searchable, draggable in Mail App)?
Background:
I am using Mountain Lion and Mail App and running out of space on my small primary SSD drive (where I keep OS, apps, key user preferences/data and mail for speed). The mail data is the big variable (many GBs) and I want to "archive"/move some of the old mail to my 2nd drive inside the Mac. But I still want it searchable inside spotlight and preferably even inside Mail too. And I'd like to be able to still drag and drop old mails into this archive folder.
What I've tried that seems to work:
This seemed to work:
1. Move the archive folder/mailbox to the 2nd drive/partition/folder (don't delete anything inside Mail App)
2. Create a symbolic link from its new location to the original/old location
This seems to work, it looks as "normal" and as if nothing happened inside Mail App but the folder now resides elsewhere and seems searchable etc. But I'm not sure that once caches refresh or over time with updates etc if stuff will break horribly or corrupt.
Is that the right way to "archive" mails in Mail App to another internal drive/partition to save space but still have it searchable in spotlight and visible, searchable, draggable in Mail App?
Thanks in advance!
Cheers,
Daniel

I'm having a similar but slightly different problem. My company just migrated to Gmail, and it's saving mail drafts every 30 seconds into my Trash folder.
I unchecked the "Show in IMAP" preference in the Gmail settings, but my Drafts folder completely disappeared. I went back and checked it and the folder reappeared (with my drafts still in there).
I like the idea if starting an email on my laptop and having the option of finishing it on my iPhone or iPad, so only saving Drafts locally would not be ideal.

Replace a 2003 (not R2) File Server with a 2012R2 files server and preferably keep the same machine name and IP when finished

I am wanting to replace a 2003 (not R2) File Server with a 2012R2 file server and preferably keep the same machine name and IP when finished. For the moment I just need some "high level" guidance, little details can be worked out once I know
which direction I will go. I was considering that DFS might be a way to help get through the process although when finished the 2012R2 Files server will be by itself with no other file server planned at this time. DFS can stay installed for maybe
future purposes but clearly I wouldn't need the DFS Replication with only one machine.
Here's a few details of the environment....
1. DC's are 2012R2 but it is still 2003 DFL because the old 2003 DCs are still present. But likely they will be gone and the DFL elevated before I start on the File Server project
2. Nearly all machines in the facility have a shortcut on the "All Users" Desktop that points to the existing old File Server. Editing or replacing that shortcut would be a major pain,...hence why I want to keep the same machine name at least,
and maybe the same IP if not too much trouble. This way the existing shortcut would continue to work with the new 2012R2 File Server. The UNC path represented in that shortcut is also configured into one or more of our major business applications,
futher emphasizing the need to keep the UNC path the same throughout the process.
3. The facility runs 24/7/365 but is "light" on weekends. The political environment is such that there is little to no tolerance for any down time at all.
4. Would DFS (based from the 2012R2 machine) be a good tool to get where I need to go?
Thanks for any suggestions.

Hi Sharon,
I've done some more reading and have a few new ideas to run past you....
Yes regular DFS wouldn't help and the Namespace would still be different than how it was with just the old server. However I was thinking DFS Replication could replace the purpose of RoboCopy and it would keep the two locations "in sync" until I was ready
to flip over to the new server. DFS Rep can exist independently of a DFS Namespace, so a Namespace is not even needed. It needs a minimum of 2003R2 for the "later & better" DFS Rep but I believe 2003 can do an "in place" upgrade to 2003R2, so I would upgrade
the old server to 2003R2 first. As long as the DFS Rep on 2012R2 and 2003R2 will properly interact I think that will work.
Thanks for the reg info on the Shares. I'm debating if editing that would reg file would really be much better than manually creating the Shares on the new server while the DFS Replication was doing its job. I'll probably export that Key as a
safety move whether I use it or not.
Once the DFS Rep is fully in sync and the Shares are in place on the new server, I figure I would then:
1. Remove the DFS Replication Object (optionally remove DFS Services completely)
2. Rename the old File Server to something else and set it to DHCP
3. Rename the new File Server to the name I want to use and give it the IP the old server had.
How does that sound?

Fstab and relatime/noatime

Hi
I just edit my /etc/fstab file and change my root and home partition to relatime, because my system becomes somehow sluggish and HHD loud after couple of days of uptime. My /etc/fstab:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
tmpfs /tmp tmpfs nodev,nosuid 0 0
/dev/sda1 / ext4 defaults,relatime 0 1
/dev/sda2 /home ext4 defaults,relatime 0 1
/dev/sda3 /media/Multi ext4 defaults 0 1
/dev/sda5 swap swap defaults 0 0
What else should i do to boost it in fstab file?
Also, what is your fstab and what do you propose to boost your system in the context of fstab file.

You can most probably use noatime rather than relatime.
Have you use it only for root partition or home and other partitions too?

Missing fstab and lilo.conf

Hello,
I browesed around in my Arch today - it's been runing for months now without a glitch and I noticed something a bit odd...
I don't have /etc/fstab and /etc/lilo.conf...
This I find odd becaus It does mount my files the way I want them and I still have my boot options the way I want them...
I did locat fstab and found a file names /etc/fstab~
and also found these :
/etc/fstab.pacnew
/etc/lilo.conf.pacnew
which look like very basic configurations and not exactly what I have on my comp...
So, so far everything is running, but it does kind of disturbs me...
So, anyone knows where my files might have gone? could one of the "pacma -Syu" made them go away or something...
I would appreciate any insight...
Grey

I can't imagine stuff loading without fstab, but maybe there's something I don't know.
Lilo.conf is not as imperative for a system to run. First, if you use grub, you'll never need a lilo.conf. Second, when you run 'lilo' it copies the data from lilo.conf to the boot partition, so the conf file isn't needed until next time you run lilo.

Fstab and auto mount

Hi, I have 2 windows partitions that I want to mount automatically at the startup, but if I set the 'auto' option, the owner of the device is root, and I have only read rights. Now I've inserted 'noauto', so I go to Konqueror and click on the device to mount it. But it's not the ideal solution. Any help?
Thanks
actual fstab
/dev/sda5 /mnt/dati vfat users,noauto,gid=users,umask=0002,rw,exec,utf8 0 0
/dev/sda2 /mnt/windows vfat users,noauto,shortname=mixed,auto,gid=users,umask=0002,rw,exec,utf8 0 0

Check `man mount` for uid and gid and mask options for the partition's filesystem. Maybe the user or users option can be interesting and altering the rights of the mount point, too.
Describe exactly what you want, if you can't figure it out with the manpage. E.g. which user and group should own the "partition", which right's shall be applied to folders and files, etc.

After installing or upgrading to Firefox 31, starting Firefox does not show homepage, customize shows a blank page and the option button does not work

I am the Windows admin for a university department and install PCs with Firefox all the time. This problem does not happen with every PC I maintain, only a select few (different model laptops with Windows 8.1 and update 1.) Until today, it only happened with new user accounts (with admin rights) that I setup on the laptops for our staff. Today this happened with The Administrator account while setting up a new laptop. In all cases so far, I install Windows from a saved image that was created using sysprep.
I have tried the many suggestions of resetting Firefox, deleting the users Firefox profile, deleting the users Windows profile, uninstalling/reinstalling Firefox, uninstalling/reinstalling Firefox and the latest Java, but nothing helps. After uninstalling, I run an app to delete temp files and caches and will even manually remove registry keys HKLM\SOFTWARE\Mozilla and HKCU\SOFTWARE\Mozilla. Plus I reboot and make sure the install folder is deleted after uninstall.
Results are the same: after installing Firefox 31, the initial setup window for migrating IE and/or Chrome pops up and after clicking the Finish button, Firefox starts, but does not show the initial new user page, only a blank page. Clicking on the Options button (3 bars) does nothing. Right-clicking in the proper area, the popup menu appears so I can choose to Customize, but that only opens another tab with about:customize in the URL and the page is blank. From the right-click popup menu, I can enable the Menu Bar and get to Options from that.
My latest attempt has helped a little. I uninstalled Firefox 31, cleaned up, deleted user Firefox profile, rebooted and then installed Firefox 30. Inital startup runs, and tells me I'm not up to date, and the Options button works. But I still cannot customize.
I then upgraded to Firefox 31, but then it's back to no startup page, no options button and no customize. I can downgrade to 30 and get all but customize working again.
Only Addon is one for McAfee Scriptscan for Firefox 15.1.0, which just after installing is disabled.
Any help would be appreciated. Thank you.

Ok. I disabled hardware acceleration. The only extension is the McAfee Scriptscan for Firefox 15.1.0, which was already disabled. I then disabled all plugins (Acrobat, Google Update, Intel Identity Protection (2x), Java Deployment Toolkit, Java Platform, MS Office 2013, Quicktime, Shockwave, Silverlight), which were all up to date.
Normal or safe mode still has same result. No startup, no option button and no customize.
Thanks for your help. Got any other suggestions?

Hi mafiose15,
Thanks for visiting Apple Support Communities.
Restoring your iPod to factory settings is the best way to try and get it back to working order. You can use the instructions below to restore it:
How to restore iPod
Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
Download and install the latest version of iTunes if necessary.
Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
Click Restore.
If you are using a Mac, you will be asked to enter an administrator’s name and password.
A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
Leave iPod connected to computer to complete restore (typically applies newer iPod models).
During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage.
Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time.
You can find the instructions in this article:

How many ways Checks can be reprinted, apart from FBZ5 and "Void and reprint" Options

Hello All - Some times, when there is issue with Printer, Checks are not printed. In such a case, Users ask us how to print Checks.
Some options I know are that (1) Checks can be reprinted through T Code - FBZ5 and
(2) if Users are Ok with voiding Checks and use next available Check numbers, We use the option in the Variant - "Void and reprint" Option.
Some Users are not happy with this Solution as they do not want to waste Checks.
I am aware of only these 2 options. Can you please suggest me other alternatives we have to reprint Checks. Your valuable inputs are very helpful to us in this regard.
Thanks

Hi Hoysala,
Please use the the FBZ5 as per attached screenshot for reprint check.

How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?

Hi All,
Hope to you a very happy new year,
I have two differnt LAP 1300 and 1200 in my network and I need to add theme to the WLC,
I successed to add one of theme by the option 60 in the DHCP pool at the Core SW,
So my quetion is below:
How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
Thanks in Advanced,
Ahmed,

To add to Scott's post. Option 60 would be useful if you needed to put certain types of AP on specific controllers. Otherwise, no real need to use it for the most part.
Though, I do recall an issue a few years ago that some windows machines had issues getting DHCP if option 43 is being returned.
Now, on an IOS switch, you can only configure one option 60 per DHCP scope
HTH,
