comment error when install library ubuntu 10.10
10.10 has been end of life and unsupported for years. You need to use a supported release or your system will quickly be hacked using unpatched vulnerabilities.

comment kexec doesn't unmount root filesystem
Looks like a bug in systemd ( or rather its units/scripts ) which you should report to debian. It should be remounting the filesystem read-only as the last thing that happens before the call to kexec, which would prevent this from happening.

comment Can't figure out what all these sd drives are
Instead of pictures, copying and pasting the text would be better, but yes, it seems that vmplayer is emulating a whole ton of virtual disk drives that are each only one sector long, which seems to be a rather silly thing to do.

Looks like vmplayer is doing something silly. What does lsblk show?

comment Why does btrfs refuse to convert metadata to RAID1
That should do it.. are you sure you let it finish? iirc, the command returns immediately while the balance goes on in the background.

comment Io redirection vs file logging performance c/c++
Why don't you try it and see? It should be pretty much the same since printf just calls fprintf on file descriptor 0.

comment What memory is not used by processes and freed by `echo 3 > /proc/sys/vm/drop_caches`?
@Halfgaar, no, the +/- cache line only counts the main data cache. The dentry cache is part of the kernel slab. It is normally much smaller than the main data cache, but can be quite significant if you are working with many ( as in hundreds of thousands or millions ) of small files.

comment Writing ISO file to USB
I don't know if it matters in this case, but one thing you are doing wrong is running mkfs on the whole disk, instead of a partition. USB sticks, like hard disks, usually need to be partitioned and then you put a filesystem in the partition.

comment Schedule backup with notification?
If you have to be sitting there to click the ok button anyhow, then why bother with scheduling? Just run the backup manually.

comment I can read from hard disk, but I can't mount it read only
The fact that the device has the .01 extension indicates that you have the controller set in IDE emulation mode and it is pretending the sata disk is an IDE slave drive. This prevents proper error diagnosis. Going into the bios and putting the controller into AHCI mode should at least get you better, proper, SATA error messages.

That is to say, that generally fan control is done in hardware and is outside of control for the os.

comment Can I mount half an ext4 partition
What do you mean "migrated"? If it was raid0, then you only have every other block of data if one of two drives failed, which is useless. If it was just concatenated drives, then you may be able to recover some of it.

comment Kernel's cached memory can't be freed, even dropping caches
Check df. You probably have a tmpfs mounted somewhere that has filled up.
