kde app 17.08, kde opening session and dolphin very slow

Opensuse 42.2 x86_64

i use these repos;
kde extra
kde app
kde framework5
qt 5

today 2017 08 21

kde session opening is very slow (several mn) and there are many many disk accesses
dolphin opening is very slow (several s) and there are many many disk accesses
dolphin displaying folder contents is very slow (several s) and there are many many disk accesses

no problem with other app as okular for example
but
using file picker in okular : several s to display the folder contents and there are many many disk accesses

root partition : 12.5 GB free
home partition : 500 GB free

if i launch dolphin in konsole i get this :

@linux-9vc6:~> dolphin
kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find “stash”
Couldn’t write “/home/roubach/.config/baloofileinformationrc” . Disk full?
qt.accessibility.core: Cannot create accessible child interface for object: PlacesView(0x17af7c0) index: 29

info : these last days there was many updates of kde applications and kf5

ok i found : home partition (xfs) is corrupted

i made a “xfs_repair” then no more problem.

i lost some folders and files.

i will restore them with luckybackup
