Thank you all for answers!
Really, I have running out of inodes,
[client]$ lfs df -i
UUID Inodes IUsed IFree IUse% Mounted on
lustre-MDT0000_UUID 13111096 13111096 0 100% /mnt/lustre[MDT:0]
lustre-OST0000_UUID 57778176 1457730 56320446 2% /mnt/lustre[OST:0]
lustre-OST0001_UUID 61054976 1457660 59597316 2% /mnt/lustre[OST:1]
lustre-OST0002_UUID 61054976 1457725 59597251 2% /mnt/lustre[OST:2]
lustre-OST0003_UUID 61054976 1457397 59597579 2% /mnt/lustre[OST:3]
lustre-OST0004_UUID 61054976 1457619 59597357 2% /mnt/lustre[OST:4]
lustre-OST0005_UUID 61054976 1457623 59597353 2% /mnt/lustre[OST:5]
lustre-OST0006_UUID 61054976 1455512 59599464 2% /mnt/lustre[OST:6]
lustre-OST0007_UUID 61054976 1455511 59599465 2% /mnt/lustre[OST:7]
lustre-OST0008_UUID 61054976 1455479 59599497 2% /mnt/lustre[OST:8]
filesystem summary: 13111096 13111096 0 100% /mnt/lustre
Would you be so kind to give me the advice How can I tune number of
inodes without loss of data? And which number of inodes I need? I’m
newbie in Lustre.. If I'll set -N 20000000 to create 2 millions of
inodes it will take 2000000*512/(1024*1024) = 9765.625 MB of MDS
capacity? (Inode size is near 512 bytes, isn't it?) Where can I look the
inode size?
Thank again!
Regards,
Katya

Hi,
Looks like your file system is running out of inodes. Please do lfs df
-i on client and copy the output here.
best regards,
