comment Why dir contents get deleted with chattr +a?
No, as he showed it works fine on a directory and prevents removing files from it.

comment The tool thin_delta segfaulting
Whether it is or is not, the program is not supposed to segfault.

lvs will tell you how much space each is using.

comment The tool thin_delta segfaulting
You will need to report a bug to CentOS then, not us. Also segregating has nothing to do with segfaulting.

comment Unable to write to disk but disk isn't full
Actually the mapping is quite linear and reliable. Each error code translates to a specific string when handed to perror(), hence, you get the appropriate error message telling you whether the disk is full, or simply mounted read only.

comment Unable to write to disk but disk isn't full
Nope; been that way for 30+ years. A write to a read only fs returns -EROFS; a write to a full fs returns -ENOSPC.

comment Unable to write to disk but disk isn't full
No actually; when the filesystem has been remounted read only you get an error that states the filesystem is read only, not out of space.

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.
