Hello,
In my setup there are three automount mount points. They are all ldap maps. The
nfs shares are on the same nfs server. nfs client and automount is on a debian
system, nfs server is a solaris one.
The problem is, trying to mount a nonexisting directory fails immediately with
the message, "No such file or directory" in two of the shares. But the third
share waits for 10-30 seconds before giving the error. The maps have 1, 9 and
19 items respectively.
I have run strace on the different automount processes. The quick ones show a
query to ldap server, then a reasonable amount of mtab stats & reads, then they
finish. The process for the slow mount point queries ldap, gets mount map,
then for about 100000 times; opens mtab file, reads contents and then closes it.
the trace file is full of these;
open("/etc/mtab", O_RDONLY) = 7
fstat64(7, {st_mode=S_IFREG|0644, st_size=1733, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0xa7afb000
read(7, "/dev/sda1 / ext3 rw,errors=remou"..., 4096) = 1733
close(7)
Any pointers to where should I look ?
