You are out of inodes. It's likely that you have a directory somewhere with many very small files.

Run diskmgmt.msc just like previous versions of Windows.

There exist no way at all to (optically) read a disk serial number once the disk is inserted into the system - the holes in the front of the disk caddy are not meant to facilitate reading a serial number but are there out of thermal and/or design considerations. This is generally true for every server/disk array manufacturer. Usually, you replace disks by ...

2 Terabyte limit on MBR disks. Convert the disk to GPT for > 2TB. Edit: For completeness - Back up all your data first. Wipe out all the partitions and volumes on the disk. Then right-click on the disk itself on the left hand side and choose "Convert to GPT."

From the man page:- "vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp" changes the name of the Volume Group with UUID Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to "VolGroup00_tmp". ...so for your case:- vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname ...will rename the volume group with ID zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-...

Every EC2 instance can access a REST endpoint at the link-local address http://169.254.169.254 that provides access to metadata about that instance. Block device mapping of EBS and instance store volumes are one of several properties available there, and the data is easily accessed from the shell and scripts using a tool like "curl." http://docs....

From what you describe, the main problem is that they decided to use a RAID5 for such a large array, which is quite a bad choice for this setup, for exactly the reason you experience: Having a 2nd disk fail during the recovery breaks everything, and this second failure is all too likely to take that risk. If they had used e.g. a RAID6 instead, having a ...

Supermicro is rough... But so is your hosting company!! There's no excuse for that. Ask for a credit on your monthly bill for the mistake if it caused downtime. So think of this: The disk serial number should be irrelevant. Replacements should be based on model number. (One of the downsides of DIY Supermicro hardware is that you aren't dealing with a ...

In the interest of preserving the information in case the TechNet article moves, here is how to "activate" the Microsoft disk cleanup utility on server 2008 or 2008 R2: Windows Server 2008 R2 64-bit C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7da\cleanmgr.exe Windows Server 2008 R2 ...

I've used 'junction' by sysinternals to redirect folders like the software distribution directory, or windows search. You can also use the built in mklink command, but junction works on older versions of windows and can be standardized against in automated deployment scripts. It works wonders for getting a server install running off of a space restricted ...

TL;DR: You can't do that. If you really want to do that you have to use sort of a storage virtualization stack on top of your disks. Something like HPE VSA will use your existing partitioning and allow to expose PART of your storage pool to external consumers.

Windows Server 2008 and newer versions will automatically align partitions optimally. There's nothing you need to do. This was a problem in older versions of Windows. The first paragraph in the summary section of this Disk Partition Alignment Best Practices for SQL Server whitepaper makes mention of this functionality (the paper is SQL Server-related, ...

Apparently, the OP has an answer for their particular problem. However, for completeness, the OP's symptoms can also occur if the filesystem has been remounted read only. This has happened to me using a Linux VM whose storage was on a clustered disk system suffering rare intermittent faults. Occasionally, the faults would cause the filesystem(s) to be ...

Don't use /dev/sd*, as they map to single paths only. Use /dev/mpath* devices (or as shown by the output of multipath -l). The output multipath -ll shows that the disk you want to use is /dev/mapper/mpath1 Make your filesystem on it, format it, partition it or what ever you like. Just don't use the /dev/sd* devices. looking at your output, mpath1 (...

What you're looking for is bind mounts. See http://man7.org/linux/man-pages/man8/mount.8.html for details. Here is a step by step guide to moving /home, /opt, /tmp, /usr, and /var to a single separate partition. Disclaimer I am not responsible for any damage or loss of data caused by following this guide. As always, ensure all important data is backed up ...

It is really easy to get to by default. You will probably even be a bit annoyed you didn't notice it. Simply right-click on the Windows logo button. Then start the Computer Management. Most of the other common tools you use for managing your system are also linked there.

I've tested this on Windows Server 2012 R2. I had a 3TB spanned volume over three 1TB disks. I just shrinked the 3TB spanned volume to 2TB in Disk management. This made all the space on the last disk unallocated. After this I was able to remove the disk without losing any data. Unfortunately this solution will not work if you want to remove the first disk ...

I hate to say this, but do you know that you were basically adding unraided disks to your pool? The command you provided basically says, "Add another disk to pool nas and stripe it with the existing disks." Is that what you meant to do? The pool is done at this point, especially if anything was written to the bad disk. If this were a pair of mirrors, the ...

Ah - just my area of specialisation! SQL 'best practices' assume that you use separate physical disk for the data and log yes, but that's in either a server with physical disks locally attached or via traditional SAN methods where a LUN was just part of a single SAN disk. EVAs are very different to this. Depending on which model you have any given LUN will ...

With that many servers, you should already have some sort of centralized monitoring solution already in place. You should investigate that solution supporting your server vendor's monitoring interface, i.e. HP Insight, Dell OpenManage, etc., because that will yield the most reliable and most useful information.

Just testing this out for myself. When converting the current system drive to dynamic I get the warning: After you convert these disks to dynamic, you will not be able to start installed operating systems from any volume on these disks (except the current boot volume). Choose to ignore this and convert anyway. However the option to mirror this drive (...

just test it on a VM with 2 vhd(x) if You are not sure. I have one very old server with windows 2003 and mirroring enabled on system drive from disk management. It works. We had incidents where the first hard drive died. When You boot the system there is an option: boot from secondary plex. We have been able to boot and make it work (it was 350km from us) ...

This right here will do ya: Event ID 2013 (Disk Is At Or Near Capacity) not getting logged To summarize, make sure you're logging disk space alerts in your event log: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanServer\Parameters] "DiskSpaceThreshold"=dword:0000000a "LowDiskSpaceMinimum"=dword:00000000 (You must add both of those, not just ...

You can do it natively in Windows, using the Windows Management Instrumentation Command-line (WMIC) interface. In this case, the command you want is wmic diskdrive, which returns the Win32_DiskDrive class. You can execute it from CMD or PowerShell. From the system I'm writing this from, for example: PS C:\WINDOWS\system32> wmic diskdrive Availability ...

That is normal, SDA2 is an extended partition, which is a special 'container' partition, that contains other partitions. An extended partitions permits you to bypass the limitation of 4 'primary' partitions that is left over for the DOS days. You should be able to resize these using gparted/parted. For safety, you can take a snapshot of your VM before ...

You can try to use a different path, not the standard one. Run in powershell: Get-Volume | fl * Find the required volume which should be optimized and copy path (it should look like - \?\Volume{787efb39-0000-0000-0000-501f00000000}) After this you can simply run defrag command with proper path: Optimize-Volume -defrag -path "\?\Volume{787efb39-0000-0000-...

Disks are enumerated by path under /dev/disk/by-path/ and via WWN under /dev/disk/by-id/. The first tell you about slot number and, by matching it with WWN, enable you to determine how slot enumeration is layed down (ie: from left to right and bottom to up, or vice versa). Most servers even have the slot themselves numbered (but be warned: I saw occasions ...

LSI RAID controllers should let the user rebuild a RAID1 array with an uncorrectable read error on source drive, resulting in a punctured array. This, however, can be implementation dependent (ie: the firmware and utils of your Oracle box may not support it). Are you sure that you can not rebuild not even using megacli? If you can't really rebuild the array,...
