I recently pulled 2.4.10, built, installed, and tested ok on a Redhat 7.1 machine. then I activated LVM module config, applied 1.0.1-rc2 LVM patches, rebuilt, manually corrected 3-ary max(), min() s to 2 arg version, as per http://lists.sistina.com/pipermail/lvm-devel/2001-September/000657.html reboot works, insmod lvm-mod installs module as expected, pvcreate, vgcreate both worked.. lvcreate segfaults however, apparently after nearly completing the LV setup. # gdb /sbin/lvcreate (gdb) r -d -L1000 -nVL_test VG_test .... <55555> pv_check_new -- CALLED <55555> pv_check_new -- LEAVING with ret: 0 <4444> pv_check_consistency -- LEAVING with ret: 0 <333> lv_check_on_pv -- LEAVING with ret: 1 <22> pv_reserve_pe -- LEAVING with ret: 0 <1> lv_setup_for_create -- pv_reserve_pe returned: 0 pe_last: 250 pe: 0 <1> lv_setup_for_create -- pe: 0 <1> lv_setup_for_create -- LEAVING with ret: 0 <1> lvm_dont_interrupt -- CALLED <1> lvm_dont_interrupt -- LEAVING Program received signal SIGSEGV, Segmentation fault. lv_create (vg=0x5, lv=0xbffff9f4, lv_name=0xbffffa0c ":ûÿ¿Rûÿ¿nûÿ¿\203ûÿ¿\233ûÿ¿½ûÿ¿Üûÿ¿èûÿ¿òûÿ¿µýÿ¿Ôýÿ¿îýÿ¿\003þÿ¿\032þÿ¿%þÿ¿0þÿ¿=þÿ¿Eþÿ¿Uþÿ¿cþÿ¿qþÿ¿\202þÿ¿\220þÿ¿²þÿ¿Ëþÿ¿Öþÿ¿áþÿ¿\024ÿÿ¿") at lv_create_remove.c:42 42 int lv_create ( vg_t *vg, lv_t *lv, char *lv_name) { (gdb) bt #0 lv_create (vg=0x5, lv=0xbffff9f4, lv_name=0xbffffa0c ":ûÿ¿Rûÿ¿nûÿ¿\203ûÿ¿\233ûÿ¿½ûÿ¿Üûÿ¿èûÿ¿òûÿ¿µýÿ¿Ôýÿ¿îýÿ¿\003þÿ¿\032þÿ¿%þÿ¿0þÿ¿=þÿ¿Eþÿ¿Uþÿ¿cþÿ¿qþÿ¿\202þÿ¿\220þÿ¿²þÿ¿Ëþÿ¿Öþÿ¿áþÿ¿\024ÿÿ¿") at lv_create_remove.c:42 #1 0x0804b03d in strcpy () at ../sysdeps/generic/strcpy.c:31 #2 0x40079177 in __libc_start_main (main=0x8049390 <strcpy+384>, argc=5, ubp_av=0xbffff9f4, init=0x8048e88 <_init>, fini=0x804b4d0 <_fini>, rtld_fini=0x4000e184 <_dl_fini>, stack_end=0xbffff9ec) at ../sysdeps/generic/libc-start.c:129 (gdb) (gdb) list 37 38 /* internal function */ 39 int lv_create_remove ( vg_t *, lv_t *, char *, int); 40 41 42 int lv_create ( vg_t *vg, lv_t *lv, char *lv_name) { 43 return lv_create_remove ( vg, lv, lv_name, LV_CREATE); 44 } 45 46 (gdb) (gdb) up #1 0x0804b03d in strcpy () at ../sysdeps/generic/strcpy.c:31 31 ../sysdeps/generic/strcpy.c: No such file or directory. in ../sysdeps/generic/strcpy.c Apriori, it looks like lv_name is uninitialized.
