I am planning on trying another brand too. I also tried using an SSD (but that one seemed to get pretty warm).. and am not sure, but the SSD made the RPI crash pretty often (wonder if that's a power (shortage) issue, since the SSD probably uses more power than a USB stick ? here are some errors I see when trying to copy data off the USB stick: Ron /var/log/kern.log.1:Jun 23 11:04:24 seismo kernel: [682577.174599] EXT4-fs error (device sda1) in ext4_da_write_end:3213: IO failure /var/log/kern.log.1:Jun 23 11:04:29 seismo kernel: [682582.102163] EXT4-fs error (device sda1): ext4_journal_check_start:61: Detected aborted journal /var/log/kern.log.1:Jun 23 11:08:00 seismo kernel: [ 1.075156] bcm2708_fb: probe of soc:fb failed with error -2 /var/log/kern.log.1:Jun 24 17:27:25 seismo kernel: [ 1.082231] bcm2708_fb: probe of soc:fb failed with error -2 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67572.665930] ieee80211 phy1: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x1700 with error -71 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.184012] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.184048] blk_update_request: I/O error, dev sda, sector 29879250 op 0x1:(WRITE) flags 0x800 phys_seg 2 prio class 0 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.307997] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.308033] blk_update_request: I/O error, dev sda, sector 29622306 op 0x1:(WRITE) flags 0x800 phys_seg 1 prio class 0 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.318950] Buffer I/O error on dev sda1, logical block 3702784, lost sync page write /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.326939] JBD2: Error -5 detected when updating journal superblock for sda1-8. /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.340483] blk_update_request: I/O error, dev sda, sector 60088192 op 0x0:(READ) flags 0x80700 phys_seg 1 prio class 0 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.357663] blk_update_request: I/O error, dev sda, sector 60088192 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0 /var/log/syslog.1:Jul 2 09:47:50 seismo kernel: [67573.368301] Buffer I/O error on dev sda, logical block 7511024, async page read /var/log/syslog.1:Jul 2 09:47:50 seismo multipathd[1602]: uevent trigger error /var/log/syslog.1:Jul 2 09:47:52 seismo kernel: [67574.717553] blk_update_request: I/O error, dev sda, sector 34 op 0x1:(WRITE) flags 0x800 phys_seg 1 prio class 0 /var/log/syslog.1:Jul 2 09:47:52 seismo kernel: [67574.727954] Buffer I/O error on dev sda1, logical block 0, lost sync page write /var/log/syslog.1:Jul 2 09:47:52 seismo kernel: [67574.735440] EXT4-fs (sda1): I/O error while writing superblock /var/log/syslog.1:Jul 2 09:47:52 seismo kernel: [67574.741426] EXT4-fs error (device sda1): ext4_journal_check_start:61: Detected aborted journal <div class="moz-cite-prefix">On 7/3/21 7:33 AM, Colin Law wrote: </div> <blockquote type="cite" cite="mid:CAL=0gLvf+7CuKZ25mmCAL5pZoV1feb72x7Gn7ii4bYFm7b9gDQ@mail.gmail.com"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> <div dir="auto">What are the IO errors? <div dir="auto"> </div> <div dir="auto">Colin</div> </div> <div class="gmail_quote"> <div dir="ltr" class="gmail_attr">On Fri, 2 Jul 2021, 23:07 R C, <<a href="mailto:cjvijf@gmail.com" moz-do-not-send="true">cjvijf@gmail.com</a>> wrote: </div> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello, I am running Ubuntu 20.04 on an RPI4, for data collection I am using a USB connected wifi dongle with long range antenna, a USB connection to an AD board, and a USB stick (formatted ext4) for storing captured data from the AD board When I try to scp data off the USB stick to somewhere else, another machine, the RPI gets really slow, I do see some IO errors in syslog and at times the RPI even 'freezes'. When I boot the same hardware with an SD card that has centos 7 installed it seems to work (not lightning fast, but consistently works). (Centos 7 is 32bit btw.) Ubuntu 20.04 is 64bit (which I want to keep using because the data logger seems to work more stable/reliable when it comes to capturing data) Any ideas what might be causing this? or where to start looking? thanks, Ron -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com" target="_blank" rel="noreferrer" moz-do-not-send="true">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" rel="noreferrer noreferrer" target="_blank" moz-do-not-send="true">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote> </div> <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
