RPM 命令掛起
在 Cent OS 5 上，
rpm命令掛在我的 Linux 機器上。[root@manage glib]# rpm -i libgcc-4.1.1-52.el5.i386.rpm [root@manage glib]# ps -efww | grep libgcc root 2020 32168 0 13:50 pts/0 00:00:00 grep libgcc root 14254 2974 0 13:09 pts/1 00:00:00 rpm -i libgcc-4.1.1-52.el5.i386.rpm下面是

rpm它不會掛起？
停止安裝命令並重建您的 rpm 數據庫。
你應該能夠：
rm /var/lib/rpm/__db*然後：
rpm --rebuilddb然後再次嘗試安裝。
我遇到了 nfs mount 的問題。rpm 擦除掛起。我無法取消 (Ctrl-C) rpm 程序。rpm 沒有理由訪問這個掛載點。
df命令也掛了。比較mount和df輸出。df 卡住的掛載是個問題。兩個坐騎對我來說是個問題。
umount /badmount沒有工作“umount.nfs：/badmount：設備正忙”。umount --force -vvv /badmounts擺脫了壞坐騎（遠端機器停機）。然後kill <my rpm process>。那麼rm /var/lib/rpm/__db* && rpm --rebuilddb。從那時起 rpm 再次工作。
rpm -vvv很有用，讓我認為坐騎是個問題。它在列印“已安裝的文件系統：”後掛起$ rpm -e --noscripts -vvv PACKAGE D: loading keyring from pubkeys in /var/lib/rpm/pubkeys/*.key D: couldn't find any keys in /var/lib/rpm/pubkeys/*.key D: loading keyring from rpmdb D: opening db environment /var/lib/rpm/Packages cdb:mpool:joinenv D: opening db index /var/lib/rpm/Packages rdonly mode=0x0 D: locked db index /var/lib/rpm/Packages D: opening db index /var/lib/rpm/Name rdonly mode=0x0 D: read h# 1489 Header sanity check: OK D: added key gpg-pubkey-57bbccba-4a6f97af to keyring D: Using legacy gpg-pubkey(s) from rpmdb D: read h# 912 Header SHA1 digest: OK (9fda42f8af7a801b81d14291987d1052d2c17c53) D: ========== --- OMN-Traffic-Control-vx.xx.xx-1.FC9 i686/linux 0x0 D: opening db index /var/lib/rpm/Requirename rdonly mode=0x0 D: ========== recording tsort relations D: ========== tsorting packages (order, #predecessors, #succesors, tree, depth, breadth) D: 0 0 0 0 1 0 -OMN-Traffic-Control-vx.xx.xx-1.FC9.i686 D: erasing packages D: closed db index /var/lib/rpm/Requirename D: closed db index /var/lib/rpm/Name D: closed db index /var/lib/rpm/Packages D: closed db environment /var/lib/rpm/Packages D: opening db environment /var/lib/rpm/Packages cdb:mpool:joinenv D: opening db index /var/lib/rpm/Packages create mode=0x42 D: mounted filesystems: D: i dev bsize bavail iavail mount pointltrace 有點意思，但沒有給出任何問題的線索。
