[Bug 491414] New: disk space problem- du: fts_read failed: No such file or directory
http://bugzilla.novell.com/show_bug.cgi?id=491414 Summary: disk space problem- du: fts_read failed: No such file or directory Classification: openSUSE Product: openSUSE 10.3 Version: Final Platform: x86-64 OS/Version: openSUSE 10.2 Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: kunal.sharma@efrontier.com QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.3) Gecko/2008101315 Ubuntu/8.10 (intrepid) Firefox/3.0.3 Hi , We are experiencing disk space issues wherein the file which occupies most disk space is /proc/kcore at 4.6GB. The file systems mounted are as Filesystem Size Used Avail Use% Mounted on /dev/sda3 12G 9.8G 1.5G 87% / udev 2.0G 80K 2.0G 1% /dev /dev/sda2 214G 60G 144G 30% /d0 nas-01.staging.efrontier.com:/vol/vol1 820G 339M 819G 1% /d0/cv/data/nas/share Now as I understand /proc/kcore is generated on fly and doesn't write to disk though it is of size of physical memory. The output of du on / gives - du: fts_read failed: No such file or directory - which I don't get on any directory under /. Is this a file system issue? I think the following outputs might be helpful release@damon:/> vmstat -am procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free inact active si so bi bo in cs us sy id wa 0 0 2101952 26396 558024 3218876 43 28 107 79 2 0 10 1 80 10 release@damon:/> cat /proc/slabinfo slabinfo - version: 2.1 # name <active_objs> <num_objs> <objsize> <objperslab> <pagesperslab> : tunables <limit> <batchcount> <sharedfactor> : slabdata <active_slabs> <num_slabs> <sharedavail> ip_conntrack_expect 0 0 136 28 1 : tunables 120 60 8 : slabdata 0 0 0 ip_conntrack 284 533 288 13 1 : tunables 54 27 8 : slabdata 41 41 0 nfs_direct_cache 0 0 128 30 1 : tunables 120 60 8 : slabdata 0 0 0 nfs_write_data 36 36 832 9 2 : tunables 54 27 8 : slabdata 4 4 0 nfs_read_data 32 35 768 5 1 : tunables 54 27 8 : slabdata 7 7 0 nfs_inode_cache 225 228 1000 4 1 : tunables 54 27 8 : slabdata 57 57 0 nfs_page 0 0 128 30 1 : tunables 120 60 8 : slabdata 0 0 0 rpc_buffers 8 8 2048 2 1 : tunables 24 12 8 : slabdata 4 4 0 rpc_tasks 8 10 384 10 1 : tunables 54 27 8 : slabdata 1 1 0 rpc_inode_cache 8 8 832 4 1 : tunables 54 27 8 : slabdata 2 2 0 fib6_nodes 5 59 64 59 1 : tunables 120 60 8 : slabdata 1 1 0 ip6_dst_cache 4 12 320 12 1 : tunables 54 27 8 : slabdata 1 1 0 ndisc_cache 1 15 256 15 1 : tunables 120 60 8 : slabdata 1 1 0 Reproducible: Always Steps to Reproduce: 1. 2. 3. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The fts_read issue has been partially known. Due to large number of directories du was failing but I still dont know the root cause which i expect from you. As far as /proc/kcore is concerened I had rebooted the system and it got right and checking dmesg didnt showed up anything as the tasks around unmounting procfs would have relvealed more information than those of mounting during starting up the system. However, the actual cause is still unknown and want rebooting here was the only immediate solution but I would like to know what caused this? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It occupies no space on any disk. I'm not seeing how this is a kernel problem.
