Checked -alm directories were in place. Proceeded with creation a few large files * also worked fine. Switched the machiine off and went to bed. Next day booted to discover that few , but the most important, dies are missing. Please advise - I'm extremely upset. Since the back is outdated. Here is a log from history I could retrive and some additional information. I run Centos 5.4 rpm based. (<a href="tel:2618164151">2.6.18-164.15.1</a>.el5.centos.plus) with lvm2 ( rpm <a href="tel:2618164151">2.6.18-164.15.1</a>.el5.centos.plus). I followed the [url]<a href="http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html">http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html</a>[/url] and here is the list of what i have (now): [code] cat /etc/fstab /dev/VG_SYS/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 devpts /dev/pts devpts gid=5,mode=<a href="tel:62000">620 0 0</a> tmpfs /dev/shm tmpfs defaults 0 0 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 /dev/VG_SYS/LogVol01 swap swap defaults 0 0 /dev/VG_Storage00/LG_VG_Storage00_00 /u01/app/ ext3 defaults 0 0 #/dev/mapper/VG_Storage01-LV_VG_STORAGE01 /mnt/storage ext3 defaults 0 0 /dev/mapper/VG_Storage-LV_00 /mnt/storage ext3 defaults 0 0 [root@server ~]# lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert LogVol00 VG_SYS -wi-ao <a href="tel:14807">148.07</a>G LogVol01 VG_SYS -wi-ao <a href="tel:89600">896.00</a>M LV_00 VG_Storage -wi-a- <a href="tel:93133">931.33</a>G LG_VG_Storage00_00 VG_Storage00 -wi-ao <a href="tel:14905">149.05</a>G LV_Backup VG_backup -wi-ao <a href="tel:23287">232.87</a>G [root@server ~]# vgs VG #PV #LV #SN Attr VSize VFree VG_SYS <a href="tel:120">1 2 0</a> wz--n- <a href="tel:14895">148.95</a>G 0 VG_Storage <a href="tel:210">2 1 0</a> wz--n- <a href="tel:93133">931.33</a>G 0 VG_Storage<a href="tel:00210">00 2 1 0</a> wz--l- <a href="tel:14905">149.05</a>G 0 VG_backup <a href="tel:310">3 1 0</a> wz--n- <a href="tel:23287">232.87</a>G 0 [root@server ~]# pvs PV VG Fmt Attr PSize PFree /dev/hdc1 VG_Storage00 lvm2 a- <a href="tel:7453">74.53</a>G 0 /dev/hdc2 VG_backup lvm2 a- <a href="tel:7452">74.52</a>G 0 /dev/hdd1 VG_Storage00 lvm2 a- <a href="tel:7453">74.53</a>G 0 /dev/hdd2 VG_backup lvm2 a- <a href="tel:7452">74.52</a>G 0 /dev/hdd3 VG_backup lvm2 a- <a href="tel:8383">83.83</a>G 0 /dev/sda2 VG_SYS lvm2 a- <a href="tel:14895">148.95</a>G 0 /dev/sdb1 VG_Storage lvm2 a- <a href="tel:46567">465.67</a>G 0 /dev/sdb5 VG_Storage lvm2 a- <a href="tel:46567">465.67</a>G 0 /dev/sdb6 lvm<a href="tel:246593">2 -- 465.93</a>G <a href="tel:46593">465.93</a>G [/code] now here is what i did. i took the sdb5 and added to VG_STORAGE, extended lvs and extended the FS. Mounted and uuuupps. half of the directories are gone. here is the history of commands. All run w/o errors. Well, at least obvious errors that would have caught my eye. [code] umount /mnt/storage vgextend /dev/mapper/VG_Storage /dev/sdb5 lvextend -l+100%VG /dev/VG_Storage00/LG_VG_Storage00_00 lvextend -l+100%FREE /dev/mapper/VG_Storage-LV_00 resize2fs /dev/mapper/VG_Storage-LV_00 e2fsck -f /dev/mapper/VG_Storage-LV_00 resize2fs /dev/mapper/VG_Storage-LV_00 df -h /mnt/storage/ Filesystem Size Used Avail Use% Mounted on /dev/mapper/VG_Storage-LV_00 932G 488G 407G 55% /mnt/storage du -hs /mnt/storage/ 487G /mnt/storage/ [/code] now, i think i mounted and checked the space. i ran a couples of commands that created a few big files in the one the directories. Everything went just fine. I never checked if all old directories exist. Today booted - and all directories/files i created after extension of the fs are in place. Some old dirs are there too. But some (~50%) are missing. Obviously, those are the ones i do care about the most.. Please help....</div></body></html>
