I have noticed that in dmesg and syslog i have something like that:
EXT4-fs warning (device sda3): ext4_dx_add_entry: Directory index full!
I have checked df -i too:
Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda3 182943744 27534820 155408924 16% /
And i see that IUse% is 16%. I rebooted that server but it's happened again. I check where i have too much files and the biggest number was 3200 files in one folder. Is it to much?
I have found in Google - that i can try fsck but how can i do it on mount system. Is not possible i think or it could crash my data.
Do you have some idea?
Thank you very much for help.
