comment Minimum requirements seem to much for a 32 bit application
@w0051977, only 4gb of ram can be mapped into the process at any given moment, but the program can change those mappings around and thus, get some benefit out of more ram. It just takes the added work of swapping around the mappings.

If your NFS server crashes, then it has a bug.. report it to your vendor or switch NFS server implementations.

comment Disk goes read-only after disabling RAID 1
10.10 has been end of life and unsupported for 4 or 5 years now. You need to nuke this system from orbit ( only way to be sure to get rid of any trojans it has been infected with due to lacking security patches for so long ), and install a supported release, probably 14.04 LTS, which will be supported for 5 years ( from april 2014 ).

comment Why doesn't MS Windows System\LocalService have the “Log on as a service” right?
Yet another example of Microsoft's broken security policy. This right is supposed to be required to run a service as that account, but it seems the service control manager is broken and happily runs services under this account without the right.

comment ESXi very slow with WD reds
Did you mean to say raid1? Check the partition tables both on the real drives and in the vm and make sure they are 4k aligned.

comment Resize RAID partition with GPT partition layout, without LVM
@thms0, no... your data is mirrored, so the idea is to break the mirror, partition the new disk the way you want it, clone the mirror to the new disk, then clone back. The shrinking of the volume is done offline and safely using resize2fs and mdadm to shrink the fs and raid array.

comment Very irregular disk write performance and repeated SATA timeouts
@DonZoomik, this makes no sense. Shingled drives can only do large sequential writes, at least to the areas that are shingled. It is when you try to do random overwrites that you run into problems since at least until operating systems become shingle aware, the drive has to internally erase and rewrite large tracks. I would imagine this internal drive emulation, not unlike SSDs, needs TRIM enabled to effectively manage this emulation, and without it, leads to this terrible sustained sequential write throughput since the drive has to rewrite data it must assume is still needed.

comment How to remove bad disk from LVM2 with the less data loss on other PVs?
@AquariusPower, actually I prefer mdadm for the raid both because I prefer raid10 over raid1, and because it can reshape the array ( lvm can't convert a 2 disk mirror into a 3 disk raid5 for instance ).

comment How to remove bad disk from LVM2 with the less data loss on other PVs?
@AquariusPower, boot should not fail if one leg of the mirror is missing. Personally I prefer to use mdadm to handle the raid and lvm on top just to divide the array up into logical volumes. Booting directly from the raid array instead of having a stand alone /boot means the system can still boot up just fine if the primary boot disk dies.

comment Is it possible to change BIOS settings from Linux?
So if you are going to downvote a question ( especially after so much time ) you're really expected to leave a comment explaining why.

comment 3disk in raid 1 using half/half
@JimB, to what docs do you refer? md(4) clearly states that it is raid10 and the number of drives need not be a multiple of the number of replicas. Just because someone wrote on wikipedia that this is called raid 1e doesn't make it so. It is raid10 because it combines striping and mirroring, plain and simple, but whatever you want to call it ( and semantic arguments are largely pointless ) it is what the OP is looking for and claiming it isn't "standard" or "enterprise grade" is simply FUD.

comment 3disk in raid 1 using half/half
To read what? Your inability to provide a rational argument does not change the facts. The fact is that I'm looking at a working mdadm 3 way raid1 right now so you are incorrect.

@mestia, you mean like Bert's answer pointed out and I commented there that those tests are misleading?
