Hi, Experts,
I have one directory like this (about 300M, over 50000 files):
/opt/xxx/usr/local/gcc-4.3-binutils-2.18
I want to create one rpm package for it, when installing the rpm
package, it should extract the files and put it to the same location
(/opt/xxx/usr/local/gcc-4.3-binutils-2.18)
finally I got the package, but when installing the rpm, it hangs
with only printing out "preparing...", then I have to kill it manually
[sstims@harry_rh52 ~]$ sudo rpm -Uvh --nodeps --nofiles
--noscript --nomd5 cs-xxx.rpm
Preparing... Killed
with help of strace, it hangs with mmap2 system call
#sudo strace rpm -ivh cs-xxx.rpm
...
mremap(0x545a6000, 1616502784, 1616506880, MREMAP_MAYMOVE) =
0x545a6000
pread64(6,
"\0\0\0\0\1\0\0\0\363\1\0\0\0\0\0\0\0\0\0\0\214\0a\7\0\2\367\17\356\17\3

mmap2(NULL, 1077669888, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x141e7000
Killed
I restart the machine and run "sudo rpm --rebuilddb", but still
failed.
If I package it with fewer files, it can be installed, but still
very slow. The most strange issue is that it need much memory when
installing the rpm package, about 800M is used, but finally hang.
Can you help to have a look on this issue?
I build the rpm package with rpm 4.0.4, and install the
package with rpm 4.4.2
I failed to create the rpm package with rpm 4.4.2,
segment fault occured.
This is a known problem of rpm < 4.7. Huge amount of files - especially with
the same basename (which shouldn't be the case here if I understood you
right) - lead to intermediate data and rpmdb requests of #files square size.
This can easily lead to memory usage beyond the 2GB address space or the
memory of even a good equipped 64bit machine. Unfortunately removing the
package takes even about double the memory... Runtime usage also gets out of
hand as you are experiencing.
Your only chance is trying a more recent rpm version which has this problem
fixed.
