hi,
Second command is running for last 1 hour and still no result, I have executed second command on another server which have same directories and configuration and it took 3 seconds and the result is 24971.

Code:

[root@racnode1 ~]# mount
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/cciss/c0d0p1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
shmfs on /dev/shm type tmpfs (rw,size=13g)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
oracleasmfs on /dev/oracleasm type oracleasmfs (rw)
none on /var/lib/xenstored type tmpfs (rw)

[root@racnode1 ~]# ls -LR /u01/app/11.2.0/grid/ |wc -l

please try df -ih on both hosts and post/compare the results

First one is the server facing problem.

Code:


[root@racnode1 ~]# df -ih
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/mapper/VolGroup00-LogVol00
30M 4.3M 26M 15% /
/dev/cciss/c0d0p1 26K 56 26K 1% /boot
tmpfs 2.0M 169 2.0M 1% /dev/shm
shmfs 2.0M 169 2.0M 1% /dev/shm
none 2.0M 4 2.0M 1% /var/lib/xenstored


-bash-3.2$ df -ih
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/sda3 7.0M 274K 6.7M 4% /
/dev/sda1 101K 57 101K 1% /boot
tmpfs 219K 274 219K 1% /dev/shm

30M 4.3M 26M 15% /
that means at about 4.3M files to count. That will take some time.

Great idea! One small suggestion: find will achieve the same thing, and might be faster if there are many files, as it doesn't need to sort them first:

Compared to 274K on the server where there is no problem. No wonder they don't perform the same ;-)

in that case ls -lRU can be used too

issue solved , problem was there are lot of trace and log files on the server of size 55 GB causing the problem i have deleted all the log and trace files now , du -sh command working fine.

Thank you all .
