As you can see from the attached terminal log below, file deletion can
take an unexpectedly long time, even if there is little disk I/O from
other tasks.
Listing the contents of similar directories (<=1000 files with ~1Gb
size) can also be surprisingly slow (several seconds for a simple ls
command).
According to nmon's disk statistics the hard drives were not
over-saturated with I/O and mostly did reads rather than writes:
xDiskName Busy Read WriteKB|0 |25 |50 |75 100|
xsdb 46% 435.7 0.0|RRRRRRRRRRRRRRRRRRRRRRRR >
xsdc 56% 461.7 0.0|RRRRRRRRRRRRRRRRRRRRRRRRRRRR >
xsdd 51% 431.7 0.0|RRRRRRRRRRRRRRRRRRRRRRRRRR >
xTotals Read-MB/s=1.3 Writes-MB/s=0.0 Transfers/sec=237.3
I see nothing strange in the kernel log and my btrfs stats are clean
from errors (and the SMART attributes are also fine):
# btrfs device stats /dev/sdb
[/dev/sdb].write_io_errs 0
[/dev/sdb].read_io_errs 0
[/dev/sdb].flush_io_errs 0
[/dev/sdb].corruption_errs 0
[/dev/sdb].generation_errs 0
(same as above for all drives)
This is a RAID-5 filesystem with 3 devices:
# btrfs fi show
Label: none uuid: 7d4769d6-2473-4c94-b476-4facce24b425
Total devices 3 FS bytes used 5.13TiB
devid 1 size 3.64TiB used 2.89TiB path /dev/sdc
devid 2 size 3.64TiB used 2.89TiB path /dev/sdd
devid 3 size 3.64TiB used 2.89TiB path /dev/sdb
# btrfs fi df /data
Data, RAID5: total=5.78TiB, used=5.13TiB
System, RAID5: total=64.00MiB, used=560.00KiB
Metadata, RAID5: total=11.00GiB, used=7.47GiB
GlobalReserve, single: total=512.00MiB, used=23.94MiB
These are fairly fast HDDs (3 equal models):
Model Number: ST4000NM0033-9ZM170
Firmware Revision: SN06
My current kernel is 4.5.1 (gentoo ~amd64) but this is not a new phenomenon.
Here is what I did for a quick benchmark (I would accept suggestions
how to measure/quantify this thing better):
# ls -Al
total 460860220

If I copy a similar folder to a freshly created Btrfs filesystem with
a single slow HDD (an old 5400RPM notebook drive with single data and
single metadata mode rather than RAID or DUP), rm takes merely a few
seconds to complete on the copy (of course, the average extents per
files are ~1.5 on the new filesystem rather than ~150 like here).
I run regular defrag on the whole filesystem (daily cronjob at
nights). This is how a recursive defrag leaves these files (and I also
run defrag on directory metadata with find).
I can think of some ways to reduce the fragmentation but I wonder if
this is normal or it's a kind of "bug" (or rather a lack of
optimization due to the development state of Btrfs RAID-5).
I tried to "tune" the io scheduler and some other kernel parameters
(as well as changing between different schedulers) and while they do
have some effects on the overall performance, it's not that much (1-5%
is not significant when one wishes for >100% difference).
