bestibnu Posted March 8, 2015 Share Posted March 8, 2015 Hi all, am facing disk space crunch only 6% left as it was a mirrored disk drive on C:\ can anyone help me to avoid less disk space, whether i have to choose to insert new disk drive or else can we extend it by adding network disk with it.

Tripredacus Posted March 9, 2015 Share Posted March 9, 2015 I am not aware of a way for you to add space to a RAID1... - what is your RAID controller?- why are you running out of space on C: drive? Link to comment Share on other sites More sharing options...
bestibnu Posted March 9, 2015 Author Share Posted March 9, 2015 I am not aware of a way for you to add space to a RAID1... - what is your RAID controller?- why are you running out of space on C: drive?As it is an dell poweredge sc1435 rack server with a built in single hard drive of 111.79 gb of mirrored disk and i found the usage of applications and users comes around 45 gb but i still have to find the remaining disk space whether it is occupied by windows updates or hidden files. In the command prompt chkdsk i found 117210208 kb total disk space107952124 kb in 366452 files 232972 kb in 65125 indexes 0 kb in bad sectors 1983920 kb in use by the system 65536 kb occupied by the log file 7041192 kb available on disk 4096 bytes in each allocation unit 29302552 total in each allocation unit 1760298 allocation units available on disk Link to comment Share on other sites More sharing options...
Tripredacus Posted March 10, 2015 Share Posted March 10, 2015 Well it looks like your server is a 1U, and you likely can't even add any additional disks into the system. Certainly you can add a network drive to the system. What is the purpose for this server? What roles and applications are installed that could potentially be taking up this space?

bphlpt Posted March 10, 2015 Share Posted March 10, 2015 You might could make use of one of the tools listed here - Visualize What Takes Up Space On Your Windows PC - to see what is taking up the space. Then you might be able to reclaim part of that space. I have used WinDirStat in the past, but one of the other tools might be better for you.

With respect to your answer is that 1U's space can't be extended and the second rack server is not listed on the network location rather it was in the device and printer list although its accessible. How can i revert it back to N/W location and suggest servers other than 1U's for enhancement. Link to comment Share on other sites More sharing options...
Tripredacus Posted March 11, 2015 Share Posted March 11, 2015 I'm guessing it is your server that can't add more disks. I looked at pictures online of your model and it appears that it only has room for two disks, and you have two already in your RAID1. It is not true that all 1U chassis can only have 2 disks! 2U gives you more flexibility as maybe you can have 4-6 disks if no ODD, or some may allow for this with slim-type drive used in notebooks. Anyways, it would appear that your current usage of the server is outliving its original design. Small pedestal servers may give enough options for future expansion... or there are the 3U and larger types used for LARGE data storage (outside of library systems).... Another option, (maybe) without having to buy new servers... maybe you can look and see if you can start storing some of this data on a network share of another computer?

Even though files are stored externally the applications and the windows folder took 75% of disk. What if the other disk unit is vacant whether it can be placed by a disk and be extended ?

Tripredacus Posted March 11, 2015 Share Posted March 11, 2015 It likely isn't. A mirror uses 2 disks. Even if you are using Software mirror from Disk Management, this is the case. A mirror means that one disk is copied to another disk, hence creating a mirror. This design is for a redundancy so that if one disk fails, it can be replaced and recreate the mirror. If you had a server with the OS on a JBOD and that disk failed, you would lose all the data and have to start over unless you kept a disk image backup. Even on the higher-end RAID controllers (which I doubt you have) you can't extend a RAID1 that I have seen. Personally, I ran into a space issue on a server a couple years ago. It had a RAID5 and there was no way for me to add space to it based on software and controller limitations. My only option was to build a new server with more space and then copy everything over. Sometimes that is just the way things work out, especially when you don't get to use the best (scalable) options because of cost or time (implementation) considerations. So for your specific problem, I would start doing some research on what exactly is taking up that space and see if it can be removed. You might be dealing with files that are not necessary, like temporary files or leftover installers. Link to comment Share on other sites More sharing options...

Is there any way to do in external drive? Also i found a link: http://blogs.technet.com/b/askpfeplat/archive/2014/05/13/how-to-clean-up-the-winsxs-directory-and-free-up-disk-space-on-windows-server-2008-r2-with-new-update.aspx Disk Management shows : C:\(System, Boot, Page File, Crash Dump) Edited March 12, 2015 by bestibnu Link to comment Share on other sites More sharing options...
Tripredacus Posted March 12, 2015 Share Posted March 12, 2015 Like I said, you probably can't extend a mirror. The WinSxS thing is one example of what could be temporary or unneeded files. Check it out. Link to comment Share on other sites More sharing options...

The point is is that a good idea ?? Edited March 12, 2015 by bestibnu Link to comment Share on other sites More sharing options...
Tripredacus Posted March 12, 2015 Share Posted March 12, 2015 What is "the application" and how is it installed? Link to comment Share on other sites More sharing options...
bestibnu Posted March 13, 2015 Author Share Posted March 13, 2015 What is "the application" and how is it installed?Adobe acrobat, ms office and some file conversion softwares also the windows folder alone occupies 38.9 GB of space i have no idea why its taking such amount of disk space?
